Devotee (2): It says in the Bhagavad-gītā that the om sound, oṁkāra, is a representation of Kṛṣṇa.
Devotee (2): Is it different from the Hare Kṛṣṇa mantra?
Devotee (2): No. Would it have the same meaning?
Prabhupāda: Not same effect. If you chant om, then you go to impersonal Brahman. But if you chant Kṛṣṇa, then you reach Kṛṣṇa, person. Just now I explained Bhagavān..., Brahman, Paramātmā, and Bhagavān. If you chant om, then you reach Brahman or Paramātmā. But if you chant Kṛṣṇa, then you reach Kṛṣṇa, Bhagavān.
