The 'I' casts off the illusion of the 'I' and yet remains 'I'. Such is the paradox of Self-realization. The Realized do not see any paradox in it. Consider the case of the worshipper. He approaches God and prays to be absorbed in Him. He then surrenders himself in faith and by concentration. And what remains afterwards? In the place of the original 'I', self-surrender leaves a residuum of God in which the 'I' is lost. That is the highest form of devotion or surrender and the peak of detachment.

The self is known to every one but not clearly. You always exist.

Engage yourself in the living present. The future will take care of itself.

The question 'Who am I?' is not really meant to get an answer, the question 'Who am I?' is meant to dissolve the questioner.

God illumines the mind and shines within it. One cannot know God by means of the mind. One can but turn the mind inwards and merge it in God.

No one succeeds without effort... Those who succeed owe their success to perseverance.

The solution to your problem is to see who has it.
