Om Namo Bhagavate Vasudevaya
We hear this before every Srimad Bhagavatam lecture. What is the benefit of chanting this mantra instead of Hari Naam (Hare Krishna Hare Krishna Krishna Krishna Hare Hare/ Hare Rama Hare Rama Rama Rama Hare Hare)? Shouldn't we simply abandon Om Namo Bhagavate Vasudevaya because it is not for this Yuga and simply chant Sri Krishna Caitanya Prabhu Nityananda Sri Advaita Gadadhara Srivasadi Gaura Bhakta Vrnda and then Hare Krishna Hare Krishna Krishna Krishna Hare Hare Hare Rama Hare Rama Rama Rama Hare Hare before starting any lecture?
Om Namo Bhagavate Vasudevaya is only to Lord Krishna in His form in Dwarka (Son of Vasudeva), but Hare Krishna is to Srimati Radhika of Vrindavana and Krishna of Vrindavana.
Please forgive me if I have made offense in asking this question.
