In simple words
Dhanu is the Vedic name for the sign Sagittarius. It is ruled by Jupiter and is dual (adaptable).
If your Moon was in Dhanu, read "As your Moon sign". If Dhanu was rising when you were born, read "As your lagna". Your chart page in Vedic mode shows both.
As your Moon sign
With the Moon in Dhanu, your mind is optimistic, principled and drawn to meaning. You need freedom and a sense of purpose to feel content. Honesty comes naturally, sometimes more bluntly than intended.
As your lagna (rising sign)
With Dhanu rising, you appear generous, frank and adventurous. Learning, faith and travel often guide your life. Following through on commitments makes your vision real.
Growing with Dhanu
Turn one big ideal into a daily practice. Dharma is lived in small steps.
Vedic signs are measured from the stars (the sidereal zodiac), about 24° behind the Western ones. That is why many people's Vedic sign is one sign earlier than their Western sign.
