The Self itself is God. - Ramana Maharshi

Your own Self-realization is the greatest service you can render the world.

That which rises in this body as 'I' is the mind. If one enquires 'In which place in the body does the thought 'I' rise first?', it will be known to be in the heart [spiritual heart is 'two digits to the right from the centre of the chest']. Even if one incessantly thinks 'I', 'I', it will lead to that place (Self).

All talk of surrender is like stealing sugar from a sugar image of Ganesha and then offering it to the same Ganesha. You say that you offer up your body and soul and all your possessions to God, but were they yours to offer? At best you can say, 'I wrongly imagined till now that all these, which are Yours, were mine. Now I realise that they are Yours and shall no longer act as though they were mine'. And this knowledge that there is nothing but God or Self, that 'I' and 'mine' do not exist and that only the Self exists is jnana. It is enough that one surrenders oneself.
