"Bhishma continued, 'Listen to me, O Yudhishthira, as I tell thee what those optional Sraddhas are that should be performed under the different constellations and that were first spoken of by Yama unto king Sasavindu. 4 That man who always performs the Sraddha under the constellation Krittika is regarded as performing a sacrifice after establishing the
sacred fire. Such a person, freed from fear, ascends to heaven with his children. He that is desirous of children should perform the Sraddha under the constellation Rohini, while he that is desirous of energy should do it under the constellation Mrigasiras. By performing the Sraddha under the constellation Ardra, a man becomes the doer of fierce deeds. A mortal, by performing the Sraddha under Punarvasu, makes such again by agriculture. The man that is desirous of growth and advancement should perform the Sraddha under Pushya. By doing it under the constellation Aslesha one begets heroic children. By doing it under the Maghas one attains to pre-eminence among kinsmen. By doing it under the prior Phalgunis, the doer of it becomes endued with good fortune. By doing the Sraddha under the later Phalgunis one attains to many children; while by performing it under Hasta, one attains to the fruition of one's wishes. By performing it under the constellation Chitra one obtains children endued with great beauty. By doing it under the constellation Swati, one makes much profit by trade. The man that desires children acquires the fruition of his wish by performing the Sraddha under the constellation Visakha. By doing it under Anuradha one becomes a king of kings. 1 By making offerings in honour of the Pitris under the constellation Jyeshtha with devotion and humility, one attains to sovereignty, O foremost one of Kuru's race. By doing the Sraddha under Mula one attains to health, and by doing it under the prior Ashadha, one acquires excellent fame. By performing it under the later Ashadha one succeeds in roving over the whole world, freed from every sorrow. By doing it under the constellation Abhijit one attains to high knowledge. By doing it under Sravana one, departing from this world, attains to a very high end. The man that performs the Sraddha under the constellation Dhanishtha becomes the ruler of a kingdom. By doing it under the constellation presided over by Varuna (viz., Satabhisha), one attains to success as a physician. By performing the Sraddha under the constellation of the prior Bhadrapada one acquires large property in goats and sheep; while by doing it under the later Bhadrapada one acquires thousands of kine. By performing the Sraddha under the constellation Revati one acquires much wealth in utensils of white brass and copper. By doing it under Aswini one acquires many steeds, while under Bharani one attains to longevity. Listening to these ordinances about the Sraddha, king Sasavindu acted accordingly, and succeeded in easily subjugating and ruling the whole earth.'"
145:4 All religious acts are either nitya or kamya. The former imply acts that are obligatory and by doing which no particular merit is acquired but by not doing which sin is incurred. The latter imply those optional acts which, if done, produce merit but which, if omitted, leads to no sin.
146:1 Literally, 'set in motion a body of kings,' i.e., become an Overlord."
