The spark of spiritual knowledge (jnana) will consume all creation. Since all the countless worlds are built upon the weak or non-existent foundation… - Ramana Maharshi

Surrender can never be regarded as complete so long as the devotee wants this or that from the Lord. True surrender is the love of God for the sake of love and nothing else, not even for the sake of salvation. In other words, complete effacement of the ego is necessary to conquer destiny, whether you achieve this effacement through Self-enquiry or through bhakti marga.

Ishta-devata and Guru are aids - very powerful aids on this path. But an aid to be effective requires your effort also. Your effort is a sine qua non. It is you who should see the sun. Can spectacles and the sun see for you? You yourself have to see your true nature. Not much aid is required for doing it!

Even if you try not to do your duty you will be perforce obliged to do it. Let the body complete the task for which it came into being. Sri Krishna also says in the Gita, whether Arjuna liked it or not he would be forced to fight. When there is work to be done by you, you cannot keep away; nor can you continue to do a thing when you are not required to do it, that is to say, when the work allotted to you has been done. In short, the work will go on and you must take your share in it -- the share which is allotted to you. [Question: How can it be done? Reply:] Like an actor playing his part in a drama: free from duality.
