dharmanam -- among religious principles; asmi -- I am; sannyasah -- renunciation; kshemanam -- among all types of security; abahih-matih -- awareness within (of the eternal soul); guhyanam -- of secrets; sunritam -- pleasant speech; maunam -- silence; mithunanam -- of sexual pairs; ajah -- Brahma, the original prajapati; tu -- indeed; aham -- I am.
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 Krishna. 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.
