Vedic Astrology (Jyotish)

Overview

概述

Vedic Astrology (Jyotish, 吠陀占星) is the traditional Indian system of astrology, literally meaning "Science of Light" (Jyoti = light, Isha = lord/science). Rooted in the four Vedas and codified in the Vedanga Jyotisha, it uses the sidereal zodiac (Niryana) — anchored to the fixed stars rather than the spring equinox — to map the positions of the Navagraha (Nine Planets). Unlike Western tropical astrology, Jyotish applies the Ayanamsa correction (Lahiri standard) to account for the precession of the equinoxes, yielding a chart that reflects actual sky positions. Tamil Jothidam (ஜோதிடம்) is the same sidereal science expressed through the Dravidian tradition, using Tamil terminology: Rasi (ராசி) for sign, Nakshatram (நட்சத்திரம்) for lunar mansion, Thisai (திசை) for Dasha, and the Navagraham (நவகிரகம்) for the nine planets.

吠陀占星學（Jyotish，吠陀占星）是傳統的印度占星系統，字面意為「光之科學」（Jyoti=光，Isha=主/科學）。它源於四部吠陀經，以恆星制黃道（Niryana）——錨定於固定恆星而非春分點——繪製九曜（Navagraha）的位置。與西方回歸制占星不同，吠陀占星應用歲差修正（Ayanamsa，以拉希里標準為主），令星盤反映真實天空位置。泰米爾占星術（ஜோதிடம்）是同一恆星制科學在達羅毗荼傳統中的表達，使用泰米爾術語：Rasi（ராசி）指星座、Nakshatram（நட்சத்திரம்）指月宿、Thisai（திசை）指運限、Navagraham（நவகிரகம்）指九曜。

The Three Pillars of Jyotish

吠陀占星三柱

Jyotish is classically divided into three branches. Siddhanta (天文算學) covers astronomical mathematics — computing planetary positions, eclipses, and the Panchangam (五支曆法: Tithi, Vara, Nakshatram, Yoga, Karana). Samhita (集成占星) addresses mundane and environmental phenomena: weather, earthquakes, national affairs, and collective omens. Hora (本命占星) is natal predictive astrology, the branch most widely studied today. Hora constructs the individual birth chart (Rashi chart, ராசி கட்டம்) from the moment of birth, then expands analysis through sixteen divisional sub-charts (Vargas) — each zooming into a specific life domain (e.g., D-9 Navamsa for marriage, D-10 Dashamsa for career). Chart styles differ by region: North Indian charts use a diamond layout with fixed houses and rotating signs, while South Indian charts use a square grid with fixed signs and rotating houses.

吠陀占星古典上分為三支。天文算學（Siddhanta）涵蓋天文數學——計算行星位置、日月蝕及五支曆法（Panchangam：月日、曜日、月宿、瑜伽、半月日）。世俗占星（Samhita）處理世俗與環境現象：天氣、地震、國事與集體徵兆。本命占星（Hora）為個人命盤預測學，是當今最廣泛研習的分支。本命占星以出生時刻構建拉西星盤（ராசி கட்டம்），再展開為十六種分盤（Vargas）分析各生命領域（如第九分盤Navamsa對應婚姻、第十分盤Dashamsa對應事業）。星盤風格因地域而異：北印度盤採鑽石形固定宮位、星座流動；南印度盤採方形固定星座、宮位流動。

The Birth Chart: Lagna, Rashi, and Bhava

本命盤：上升、星座與宮位

The birth chart is the foundational document of Hora. The Lagna (Ascendant, 上升點) — the zodiac sign rising on the eastern horizon at the exact moment of birth — is the most critical point in the chart. It determines how all twelve Bhavas (Houses, 宮位) are counted: the Lagna itself becomes the first Bhava, governing self, body, and personality. The twelve Rashis (Signs: Aries through Pisces) are distributed across the twelve Bhavas, and each of the seven visible Navagrahas plus Rahu and Ketu occupies specific Bhavas. Planetary dignity is assessed by Moolatrikona, own sign (Swakshetra), exaltation (Uchcha), debilitation (Neecha), and friendly or enemy signs.

本命盤為本命占星的基礎文件。上升（Lagna）——出生確切時刻東方地平線升起的星座——是星盤中最關鍵的點，決定十二宮（Bhava）的排列方式：上升本身為第一宮，掌管自我、身體與個性。十二星座（Rashi）分佈於十二宮中，七顆可見行星加羅睺、計都各佔其宮。行星品位以Moolatrikona、本宮（Swakshetra）、入旺（Uchcha）、落陷（Neecha）及友好或敵對星座評估。Source: Brihat Parashara Hora Shastra（बृहत्पाराशरहोरा शास्त्र），第七章——上升與宮位計算。

Vimshottari Dasha — The 120-Year Cycle

毗摩梭多里運限——一百二十年週期

The Vimshottari Dasha (विंशोत्तरी दशा) is the most widely used Dasha system, dividing a human life into a 120-year cycle of nine planetary main periods (Mahadasha). The cycle begins from the natal Moon's Nakshatra position and unfolds in fixed sequence: Ketu 7 years → Venus 20 years → Sun 6 years → Moon 10 years → Mars 7 years → Rahu 18 years → Jupiter 16 years → Saturn 19 years → Mercury 17 years. Each Mahadasha is subdivided into Antardashas (sub-periods) of the same nine planets, and further into Pratyantar (sub-sub-periods). When a Dasha planet rules or aspects key Bhavas from the Lagna or Moon, it activates the themes of those houses with intensified timing precision. Tamil Jothidam calls these Thisai (திசை) and Bukti (புத்தி) respectively. Source: Brihat Parashara Hora Shastra (बृहत्पाराशरहोरा शास्त्र), Chapter 46 — Vimshottari Dasha.

毗摩梭多里運限（Vimshottari Dasha）是最廣泛使用的運限系統，將人生劃分為一百二十年的九大行星主運週期（Mahadasha）。週期從出生時月亮所在月宿位置起算，依固定順序展開：計都7年→金星20年→太陽6年→月亮10年→火星7年→羅睺18年→木星16年→土星19年→水星17年。每個主運再細分為九大行星的次運（Antardasha），進而細分為小運（Pratyantar）。當某大運行星主宰或相位上升或月亮計算的關鍵宮位時，即以高精度時機激活該宮的主題。泰米爾占星術分別稱之為Thisai（திசை）與Bukti（புத்தி）。Source: Brihat Parashara Hora Shastra（बृहत्पाराशरहोरा शास्त्र），第46章——毗摩梭多里運限。

Shadbala — Six-Fold Planetary Strength

六力——六重行星力量

Shadbala (षड्बल, Six Strengths) is the numerical system for assessing how strongly each planet can deliver its results. It comprises six components: (1) Sthana Bala — positional strength based on sign dignity (exaltation, Moolatrikona, own sign, friendly, neutral, enemy); (2) Dig Bala — directional strength: Jupiter and Mercury are strongest in the East (1st Bhava), Sun and Mars in the South (10th Bhava), Saturn in the West (7th Bhava), Moon and Venus in the North (4th Bhava); (3) Kala Bala — temporal strength based on time of birth (day/night, lunar fortnight, seasonal, planetary day/hour); (4) Cheshta Bala — motional strength: a planet in retrograde (Vakra) or slow motion gains Cheshta Bala, indicating it is "striving" in the native's life; (5) Naisargika Bala — natural/inherent strength in the fixed order Sun > Moon > Venus > Jupiter > Mercury > Mars > Saturn; (6) Drik Bala — aspectual strength, gained or lost through aspects from benefic or malefic planets. The total Shadbala score determines whether a planet is strong enough to fully manifest its significations. Source: Brihat Parashara Hora Shastra (बृहत्पाराशरहोरा शास्त्र), Chapter 27 — Shadbala.

六力（Shadbala，षड्बल）是評估每顆行星能否充分發揮效果的數值體系，由六個組成部分構成：(1) 位置力（Sthana Bala）——基於星座品位的位置力量（入旺、Moolatrikona、本宮、友好、中立、敵對）；(2) 方向力（Dig Bala）——方向力量：木星、水星在東方（第一宮）最強，太陽、火星在南方（第十宮）最強，土星在西方（第七宮）最強，月亮、金星在北方（第四宮）最強；(3) 時間力（Kala Bala）——基於出生時間的力量（晝夜、月相、季節、行星日/時）；(4) 動作力（Cheshta Bala）——運動力量：逆行（Vakra）或運動緩慢的行星獲得Cheshta Bala，表示其在命主生命中「努力發揮」；(5) 自然力（Naisargika Bala）——固定順序的先天力量：太陽>月亮>金星>木星>水星>火星>土星；(6) 相位力（Drik Bala）——因吉星或凶星相位而獲得或失去的力量。六力總分決定行星是否足夠強大以充分顯現其所主事項。Source: Brihat Parashara Hora Shastra（बृहत्पाराशरहोरा शास्त्र），第27章——六力。

Ashtakavarga — The Eight-Source Point System

八源宮點——八貢獻者宮位體系

Ashtakavarga (अष्टकवर्ग) is a sophisticated transit and strength analysis system in which each of the seven traditional planets (plus the Lagna) casts benefic points (Bindus, 吉點) into all twelve Bhavas. Each contributor can cast a maximum of 8 Bindus to any one house, hence "Ashta" (eight). The combined Sarvashtakavarga (total Bindu count) of all eight contributors in any given Bhava indicates the collective strength and auspiciousness of that house: 28 or more Bindus is considered strong (events in that house's domain will be favourable); below 25 is weak. Ashtakavarga is particularly powerful for transit prediction: when a planet transits a house with high Bindus in its own Ashtakavarga, it produces beneficial results. Conversely, transit through a house with few Bindus brings difficulty. Source: Brihat Parashara Hora Shastra (बृहत्पाराशरहोरा शास्त्र), Chapter 66 — Ashtakavarga.

八源宮點（Ashtakavarga，अष्टकवर्ग）是一套精密的行運與力量分析體系，七顆傳統行星（加上上升點）各自向十二宮投射吉點（Bindu，吉點）。每位貢獻者最多可向任一宮投射8個吉點，因此稱「Ashta」（八）。所有八位貢獻者在某一宮的總和（Sarvashtakavarga總吉點數）反映該宮的整體力量與吉祥程度：28個或以上為強（該宮事項將順利）；25以下為弱。八源宮點對行運預測特別有力：當行星行運通過其自身八源宮點中吉點數高的宮位時，帶來有益結果；反之則帶來困難。Source: Brihat Parashara Hora Shastra（बृहत्पाराशरहोरा शास्त्र），第66章——八源宮點。

Yoga Karaka — The Supreme Benefic Planet

瑜伽因素——最高吉星

A Yoga Karaka (योग कारक) is a planet that simultaneously rules a Kendra Bhava (angle house: 1, 4, 7, 10) and a Trikona Bhava (trine house: 1, 5, 9) from the Lagna. Such a planet alone can produce outstanding Raja Yoga (royal combination) results regardless of where it is placed, because it combines the power of activity (Kendra) with the grace of dharma and fortune (Trikona). Examples: for Taurus Lagna (Vrishabha), Saturn rules the 9th (Trikona) and 10th (Kendra) — Saturn is Yoga Karaka; for Cancer Lagna (Karka), Mars rules the 5th (Trikona) and 10th (Kendra) — Mars is Yoga Karaka. This concept is critical in Tamil Jothidam (Yoga Karaka = தொழில் கிரகம், "career planet") where the Yoga Karaka period (Thisai) is expected to bring the native's peak achievements. Source: Brihat Parashara Hora Shastra (बृहत्पाराशरहोरा शास्त्र), Chapter 34 — Yogas.

瑜伽因素（Yoga Karaka，योग कारक）是同時主宰上升計算的一個角宮（Kendra：第1、4、7、10宮）和三角宮（Trikona：第1、5、9宮）的行星。此類行星無論落於何宮，僅憑一己之力即可產生卓越的王者組合（Raja Yoga）結果，因其兼具活動力（角宮）與法性吉運（三角宮）。例如：金牛上升（Vrishabha），土星主第9宮（三角）與第10宮（角），故土星為瑜伽因素；巨蟹上升（Karka），火星主第5宮（三角）與第10宮（角），故火星為瑜伽因素。這一概念在泰米爾占星術中至關重要（Yoga Karaka = தொழில் கிரகம்，「事業星」），其主運（Thisai）期間被視為命主達到事業巔峰之時。Source: Brihat Parashara Hora Shastra（बृहत्पाराशरहोरा शास्त्र），第34章——瑜伽組合。

Tamil Jothidam and Navagraha Worship

泰米爾占星術與九曜崇拜

Tamil Jothidam (ஜோதிடம்) is the expression of Vedic sidereal astrology within Tamil Nadu's Dravidian civilisation. The Tamil names of the Navagraham (நவகிரகம்) are: Suriyan (சூரியன், Sun), Chandran (சந்திரன், Moon), Sevvai (செவ்வாய், Mars), Budhan (புதன், Mercury), Guru (குரு, Jupiter), Sukran (சுக்கிரன், Venus), Sani (சனி, Saturn), Rahu (ராகு), Ketu (கேது). Tamil astrology places particular emphasis on Chevvai Dosham (செவ்வாய் தோஷம், Manglik condition) — Mars in the 2nd, 4th, 7th, 8th, or 12th house from the Lagna, Moon, or Venus creates this dosha, which is believed to create friction in marriage unless matched with a partner who has the same condition or qualifies for a Nivarthi (நிவர்த்தி, cancellation). Kala Sarpa Dosha (கால சர்ப தோஷம்) — all seven traditional planets hemmed between Rahu and Ketu — is another significant condition with twelve named types from Ananta to Sheshnag based on Rahu's house position. Navagraha temples in Tamil Nadu (Navagrahasthalangal, நவகிரக ஸ்தலங்கள்) are dedicated sites for planetary propitiation, where devotees perform specific rituals, puja, and gemstone remedies to harmonise difficult planetary influences identified in the birth chart.

泰米爾占星術（ஜோதிடம்）是吠陀恆星制占星在泰米爾納德邦達羅毗荼文明中的表達。九曜（நவகிரகம்）的泰米爾名稱為：Suriyan（சூரியன்，太陽）、Chandran（சந்திரன்，月亮）、Sevvai（செவ்வாய்，火星）、Budhan（புதன்，水星）、Guru（குரு，木星）、Sukran（சுக்கிரன்，金星）、Sani（சனி，土星）、Rahu（ராகு）、Ketu（கேது）。泰米爾占星術特別重視Chevvai Dosham（செவ்வாய் தோஷம்，火星煞）——火星落於上升、月亮或金星計算的第2、4、7、8或12宮形成此煞，被認為會在婚姻中造成摩擦，除非與同樣具此條件的伴侶匹配或符合Nivarthi（நிவர்த்தி，解除）條件。卡拉蛇煞（கால சர்ப தோஷம்）——七顆傳統行星全部被羅睺與計都夾制——是另一顯著狀況，依羅睺宮位分為從Ananta到Sheshnag的十二種類型。泰米爾納德邦的九曜廟（Navagrahasthalangal，நவகிரக ஸ்தலங்கள்）為行星息災的專用場所，信眾在此為星盤中識別出的困難行星影響進行儀式、普迦及寶石療法。
