Explanation:

God cannot be attained by the deep analysis of any item in creation including the self. The self is a part of the creation alone since it is called as Para Prakruti or the best item of the creation by the Gita. God can neither be obtained by going down deeply into the self or going down deeply into any item in creation since the self is also just an item of creation. Self may be most precious but still it is only an item or a part of creation. The reason for not touching God by going down in the creation is that the link between the unimaginable God and the imaginable creation is also unimaginable. As you cannot touch the unimaginable God, you cannot touch the unimaginable link between God and creation also.
