Param Brahma, Param Dhaama pavitram paramam bhavaan;
Purusham shaasvatam divyamaadidevamajam vibhum (Gita 10:12)
Aahustaamrshayah sarve devarshirnaaradastathaa;
Asito devalo vyaasah svayam caiva braveesi me.” (Gita 10:13)
“You are the Supreme Brahma (Eternal; Pure Consciousness), the Supreme Abode, the Supreme Purifier, the Eternal Divine Person, the Prime Deity, the Unborn, the Omnipresent. Likewise all the sages have acclaimed You, as also the celestial sage Naarda, so also Asita, Devala and Vyasa; And You Yourself, have also proclaimed, this to me.” (Gita 10:12-13)
Having used the expression “Param Brahma” for attributeless and formless Brahma; “Param Dhaama” for God endowed with attributes, but without form and “Pavitram Paramam Bhavaan” for God endowed with attributes and form, Arjuna implies to Lord Krsna that He is Universal God (Universal Consciousness, Supreme Soul) in entirety (samagra).
He who Himself is pure (holy) and also sanctifies others is “Param Pavitra” (most sacred). God Himself is most sacred, and His Name and Form etc. all are also most sacred. In Gita 4:28 Jnana (knowledge) has been declared to be the purest (most sacred) – “na hi jnaanena sadrsam pavitramiha vidyate”. But even that knowledge too is within God. Therefore God is more sacred than even knowledge.
