Before reciting the Gayatri mantra, Srila Prabhupada has advised sannyasis to chant the following mantra from Srimad Bhagavatam 11.23.57, which is part of the song sung by the Avanta Brahmana: “I shall cross over the insurmountable ocean of nescience by being firmly fixed in the service of the lotus feet of Krsna. This was approved by the previous acaryas, who were fixed in firm devotion to the Lord, Paramatma, the Supreme Personality of Godhead.” This mantra indicates that there is NOTHING in the material world worth being attached to, unless of course, it is part of Krishna Himself. SB 4.29.55 “When one is not attached to anything, but at the same time accepts everything in relation to Krsna, one is rightly situated above possessiveness.” (Bhakti-rasamrta-sindhu 1.2.255) SB 7.14.7 purport: “One who rejects anything without knowledge of its relationship to Krsna is incomplete in his renunciation.” (Bhakti-rasamrta-sindhu 1.2.256)
