Venus in Jyotisha is Shukra, 'teacher of the asuras' — paired with Jupiter, teacher of the gods. Both are teachers, both great benefics; the difference is that Jupiter teaches meaning and Venus teaches enjoyment and relationship. She governs beauty, art, love, partner, comfort, the enjoying of wealth, diplomacy, and everything that makes things approachable.
Mechanically, Venus is at home in Taurus and Libra, exalted in Pisces and debilitated in Virgo. Pisces is unconditional love: Venus's beauty there is devotional. Virgo is fault-finding and analysis: her enjoyment there gets flattened by calculation — beauty wants appreciation, not inspection. She's the brightest body nearest the earth, and speaks to the most intimate pleasures.
Where you'll recognise it: responding to beauty, caring about comfort, relationships mattering greatly, being able to improve a room, holding to your taste. Running well, Venus is your softest and most magnetic part: appreciating, attracting, letting people close, living with quality. Stuck, it's indulgence or emptiness — everything must be comfortable, the necessary discomforts avoided; or the reverse, beauty dismissed as surplus and a life lived dry. Venus's lesson is to enjoy without being seized by enjoyment: let beauty feed you, not live for you.
