Art of Revival from death

Mahabharata Adiparva Sambhavaparva section 76-77
Sri Sadgurbhyoh namah

King Janamejaya asks Vaisampayana, how his ancestor Yayati married Devayani and Sharmista. Vaisampayana recounts the story :

Long time ago, there were frequent wars between gods and demons. The priest of demons was Sukra (a.k.a Usana and Kavya), and priest of gods was Brihaspati, son of Angiras. The priest of demons, Sukra through the power of his knowledge called Sanjivini (revival from death), used to revive the demons that died in the battle, whereas Brihaspati due to lack of such knowledge was unable to do so for gods. Indra (King of gods), sent Kacha, son of Brihaspati to study that knowledge from Sukra. Kacha takes a vow of brahmacharya for 1000 years and joins the hermitage of Sukra. Kacha makes himself dear to Sukra and his daughter Devayani by sweet words, singing and dancing.

After 500 years demons come to know the plan of Kacha and kill him, hack him into pieces and make jackals and wolves eat him. Devayani entreats her father to make Kacha alive again. Sukra through the sanjivini vidya makes him alive again. Demons again kill Kacha and make him into a paste. Sukra again revives him through his knowledge upon the pleadings of his daughter.

Third time, demons kill Kacha, burn him to ashes, mix it wine and give it to Sukra to drink. Sukra drinks the wine.

Devayani again asks her father to make Kacha alive. Sukra makes him alive, but Kacha is trapped in the body of Sukra. If kacha comes out Sukra will die. So Sukra teaches the Sanjivini vidya to Kacha. Kacha then tears open the stomach of Sukra and comes out, and revives Sukra. Kacha pays respect to Sukra saying "One recieves knowledge from a preceptor, and having recieved from one, whoever does not do good for the preceptor will go to regions of sin".

Then Sukra proclaims that "As I lost senses by drinking wine, henceforth any brahmana who drinks wine is equivalent to commiting brahma hatya dosha (sin of killing brahman)".

Kacha refuses to marry devayani as he also has come from the body of same father, then goes to abode of gods and teaches them sanjivini vidya.

My commentary :

There are few things to note,

1) A brahmana should not drink wine

2) A preceptor gives knowledge, and one should do good to preceptor

3) To attain knowledge one has to die three times (I will leave commenting further)
