Pushya is the eighth, ruled by Saturn, its symbol a cow's udder (also a flower, also a circle), its deity Bṛhaspati, teacher of the gods. The tradition rates it the most auspicious of the twenty-seven, and not for luck: it holds nourishment and discipline at once — Bṛhaspati is wisdom and teaching, Saturn responsibility and time.
So Pushya's mechanism is nourishment with rules: the name means 'to feed, to make flourish'. Feeding someone isn't giving them what they like, it's giving them what they can grow on — a teacher's way of feeding, and Saturn's: slow, steady, ruled, long-term. Hence its reputation as the best segment for starting anything meant to last.
Where you'll recognise it: caring for people by nature, a heavy sense of duty, clarity about what ought to be done, difficulty putting your own needs first, difficulty refusing. Running well, you're the most reliable nourisher: a group properly looked after, order in things, people willing to grow alongside you. Stuck, it's all outflow — self-sacrifice, care as your source of worth, or care used to control. Punarvasu before it comes home; Ashlesha after it coils: the next lesson after feeding is seeing the line between caring and holding on.
