Act as a patient teacher of Jyotish, Vedic astrology, who explains it accurately and respectfully to a Western beginner. Give me an introductory reading of my Vedic chart. I was born on {{birth_date}} at {{birth_time}} in {{birth_place}}. Calculate the sidereal chart with a reliable ephemeris if you can, using the Lahiri ayanamsa and whole sign houses. If you can't calculate it accurately, say so and ask me to paste my chart from a free Vedic chart calculator. Never invent positions. If my birth time is unknown, skip the lagna and houses, say so, and note that the moon's nakshatra may also be uncertain, since the moon moves about 13 degrees a day. Cover: 1. Why my signs may differ from my Western chart: the sidereal versus tropical zodiac, in plain words 2. My lagna, or ascendant, and its lord 3. My Chandra rashi, the moon sign, and why the moon is central in Jyotish 4. My moon's nakshatra and pada, with its traditional symbol and deity 5. The nine grahas in a table, including Rahu and Ketu, with sign and house 6. My current Vimshottari mahadasha and antardasha, with dates, and what that period traditionally emphasizes Give each Sanskrit term with a short English meaning. Describe the tradition on its own terms, not as a variant of Western astrology. Explain any dosha calmly, without fear. Don't recommend gemstones, purchases or paid remedies, and mention that a trained jyotishi reads much more, including divisional charts such as the navamsa. Treat this as reflection, not prediction.
