Nakshatra

Nakshatra (Sanskrit: नक्षत्रम्, romanized: Nakṣatram) is the term for lunar mansion in Hindu astrology. A nakshatra is one of 27 (sometimes also 28) sectors along the ecliptic. Their names are related to a prominent star or asterisms in or near the respective sectors. In essence (in Western astronomical terms), a nakshatra simply is a constellation. Every nakshatra is divided into four padas (lit. "steps") related to the Char Dham, a set of four pilgrimage sites in India.

The starting point for the nakshatras according to the Vedas is "Krittika" (it has been argued because the Pleiades may have started the year at the time the Vedas were compiled, presumably at the vernal equinox), but, in more recent compilations, the start of the nakshatras list is the point on the ecliptic directly opposite to the star Spica, called Chitrā in Sanskrit. This translates to Ashvinī, a part of the modern constellation of Aries. These compilations, therefore may have been compiled during the centuries when the sun was passing through Aries at the time of the vernal equinox. This version may have been called Meshādi or the "start of Aries".^{[1][full citation needed]}

The first astronomical text that lists them is the Vedanga Jyotisha.^{[2][better source needed]}

In classical Hindu scriptures (Mahabharata, Harivamsa), the creation of the asterisms is attributed to Daksha.^[3] The Nakshatras are personified as daughters of Daksha and as wives of Chandra, the god of the Moon. When Chandra neglected his 26 other wives in favour of Rohini, his father-in-law cursed him with leprosy and proclaimed that the Moon would wax and wane each month.^[4] The Nakshatras are also alternatively described as the daughters of Kashyapa.
