Arthashastra
त्रि रात्र उपोषितः पुष्येण शस्त्र हतस्य शूल प्रोतस्य वा पुंसः शिरः कपाले मृत्तिकायां गुञ्जा आवास्य उदकेन सेचयेत् ॥
Having fasted for three nights and having on the day of the star of Pushya planted gunja seeds in the skull, filled with soil, of a man killed with weapons or put to the gallows, one should irrigate it with water.
