Similar is the case with Punyaka vrata. O virtuous one, you perform this vrata which is difficult to get in the three worlds. With the influence of this vrata you will achieve an influential son. 

Lord Krishna happens to be the, main deity of this mantra who fulfils all the desires and by adoring whom one redeems crores of his generations. 

Whosoever recites the mantra of the lord in the land of Bharata, his life meets with success.  He also redeems crores of his generations and ultimately achieves Vaikuntha where he serves as a courtier of lord Krishna and spent his life conformably. 

Such a person after redeeming his brothers, servants, associates and the ladies of the household, proceeds to the house of the lord. О Parvati, therefore, you accept the mantra of the lord which is difficult to get and which redeems the manes; thereafter, lord Shiva went to the bank of Ganga together with Parvati and imparted the knowledge of the sacred mantra of the lord of Parvati. О sage, he also explained to her the kavacha, stotra and method of adoration to her.
