Hasta is nakshatra number 13 of the 27 lunar mansions in Vedic astrology, spanning 160.00° of the zodiac in 13°20' steps. Its planetary lord is Moon and its presiding deity is Savitr.
The Moon's position in Hasta at birth shapes the Vimshottari Mahadasha sequence — a Hasta birth begins life in the Moon mahadasha, with the balance of that period decided by how far the Moon had travelled through the nakshatra.
