When your intelligence, crosses the quagmire of delusion, then will you grow indifference to whatever you have heard and are yet to hear.
When the seeker pursues his spiritual sādhanā rigorously, mind and intelligence are the only factors to be dealt with finally. And intellect’s doubts are the final obstacles. This has to become clear to the seeker.
The ultimate doubts are caused by the differing statements of the scriptures themselves, which are the ultimate spiritual source of guidance. What to do then with the conflicting scriptural statements? It becomes a quagmire, which the seeker finds extremely hard to cross.
Krishna says, it is the basic delusion about the Self that distracts the seeking mind this way and that. When the seeker is able to be rid of his delusion, then will he become so confident and clear that he will grow indifference to all doubts and enquiries, even if they are caused by scriptures: “Enough of it all. I have to realize I am the Self, not the body. This direct experience alone will fill me in full. The mind has to be still and intelligence doubt-free. I am quite stable now.”
