udho! man na bhayo das bis
eka huto se gayo syama sanga ko avaradhe isa.
"O uddhava! we have only one mind and that is with shyamsundar(krishna).if we had many mind.then we could have used each one in different direction. and manage both devotion to god and world" but God was aware of fact that if each individual was to be given two mind.no one would able to fulfill the "mamekam shranam braj" ie.surrender to God alone.
to conclude surrender of mind alone to God.whatever the physical action be.now the question is what is the difficulty in surrender of mind?the only difficulty is that the mind has been attached to the material world since time immemorial and the attachment has become very firm.had the mind been nither attached to the world nor to God.then surrender would have been effortless.hence the first step is to detch the mind:this can be achived through an understanding of the reality of the world to god be possible.
