Pashupata-sutra should not be confused with Pashupatastra.
Pashupata-sutra (IAST: Pāśupatasūtra) is a Sanskrit-language text regarded as revelation by the Pashupata Shaivite sect of ancient India.[1] Dated between 400 and 550 CE,[2] it is the earliest surviving text of the Pashupatas.[1] Kauṇḍinya wrote a commentary called Panchartha-bhashya (IAST: Pañcārtha-bhāṣya) on the text.[3]
In the text, Shiva enters the dead body of a Brahmana, which comes to life as Lakulisha and imparts teachings to four disciples.[1]

The text states that the aspirant's sins pass over to his abusers, and their merits pass over to him. Examples of these anti-social behaviors include:
Next, the aspirant enters the third stage, where he should:
The text states that after following these practices, the aspirant unites his soul with Shiva. After six months in this union, he starts living in a cremation ground, survives on whatever is available, and finally dies. He thus unites with Shiva, and ends all his sorrows through Shiva's grace.
