Srimad Bhagavatam Canto 11, Chapter 16, Text 26

SB 11.16.26

dharmanam asmi sannyasah
 ksemanam abahir-matih
guhyanam su-nrtam maunam
 mithunanam ajas tv aham
Among religious principles I am renunciation, and of all types of security I am consciousness of the eternal soul within. Of secrets I am pleasant speech and silence, and among sexual pairs I am Brahma.
One who realizes the eternal soul within no longer fears any material situation and thus is qualified to accept the renounced order of life, sannyasa. Certainly fear is one of the great miseries of material life; therefore the gift of fearlessness is very valuable and represents Lord Krsna. Both in ordinary pleasant speech and silence, very few confidential things are revealed, and thus diplomacy and silence are both aids to secrecy. Lord Brahma is prominent among sexual pairs because the original beautiful couple, Svayambhuva Manu and Satarupa, emerged from Lord Brahma’s body, as explained in Chapter Twelve of the Third Canto of Srimad-Bhagavatam.
