Lord Vishnu is known as Mahavishnu, the legendary deity among trinity that rescue the life from hurdles of journey and help the soul for the cause, indeed ever keeps favor for devotees and Brahmans, Vishnu Means, the one pervades, one who manifest with a call perhaps may in different entity to justify the truth and help the cause, Vishnu is transcendent as well as the immanent reality of this universe, It is Lord Vishnu that manifest in the form of sri Pitar Dev along with souls of ancestors , here souls are cows and Vishnu is cowherd, Brahmans are the medias to feed the cows felicitated by Mahavishnu, Pitar Paksh is right here to serve the cause through service of True Brahmans to gratify the soul of ancestors, May Lord Bless all-thanks
