Every Vedic mantra is called brahma because each mantra is preceded by the brahmÄká¹£ara (aum or oá¹kÄra). For example, oá¹ namo bhagavate vÄsudevÄya. Lord Kṛṣṇa says in Bhagavad-gÄ«tÄ (7.8), praṇavaḥ sarva-vedeá¹£u: “In all the Vedic mantras, I am represented by praṇava, or oá¹kÄra.†Thus chanting of the Vedic mantras beginning with oá¹kÄra is directly chanting of Kṛṣṇa’s name. There is no difference. Whether one chants oá¹kÄra or addresses the Lord as “Kṛṣṇa,†the meaning is the same, but ÅšrÄ« Caitanya MahÄprabhu has recommended that in this age one chant the Hare Kṛṣṇa mantra (harer nÄma eva kevalam). Although there is no difference between Hare Kṛṣṇa and the Vedic mantras beginning with oá¹kÄra, ÅšrÄ« Caitanya MahÄprabhu, the leader of the spiritual movement for this age, has recommended that one chant Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare RÄma, Hare RÄma, RÄma RÄma, Hare Hare.
