Hari Om. Pranams.
My Reflections on name "BHAAVAH: One who " becomes" Himself into the movable and the immovable beings and things in the world" -
One can 'become' only THAT which one is NOT.
So we can say, that which is NOT movable and immovable beings and things in the world THAT is our dear Shri Lord. He is Nirgun that is why He "becomes" Sagun.
World is Jagat (Ja-jayate(takes birth), Ga- Gacchati(goes or dies), Ta - Tishthati Iva(appears to stay in between birth and death)).
Lord becomes all the things and beings that take birth, appear to stay and then die away. So we can say "I am breathing Lord, I am eating Lord, I am walking on Lord, I am touching Lord, I am thinking Lord, my nose is Lord, my mouth is Lord, my legs are Lord, my body is Lord, my mind is Lord...and so on" Just like when two clouds clash with each other, lightening happens; when Lord as "experiencer" touches Lord as "experienced object" experience happens. When Lord as "knower I" beholds a notion of Lord as "This object" knowledge happens. Since experience and knowledge keep changing it is part of world and Lord has "become" that. Finding Lord through this show of "appearances" of Him is possible only by shifting our focus from all appearances (world). Since "Finding" is also "becoming" I think when we stop all our "trying to find" and "just be", then Lord will find us in Him.
