(Kadamba Kanana Swami, 25 April 2017, Radhadesh, Belgium, Srimad Bhagavatam 7.15.68)
The sound of Krsna’s flute was heard by Lord Brahma and then, the sound of that flute came out of the mouth of Lord Brahma through the Gayatri Mantra. So through the Gayatri Mantra we can hear Krsna’s flute. This makes second initiation a little more exciting. It is not only about being a brahmana. It is not only about the mode of goodness but you also hear the Gayatri Mantra which was what came out of Brahma’s mouth after hearing Krsna’s flute. It is said that the Gayatri Mantra is like the sound of Krsna’s flute in mantra form. This is very interesting, this is why it is a secret mantra!
