Meditation differs according to the degree of advancement of the seeker. If one is fit for it, one might directly hold the thinker; and the thinker will automatically sink into his source, namely Pure Consciousness.
If one cannot directly hold the thinker, one must meditation on God; and in due course the same individual will have become sufficiently pure to hold the thinker and sink into absolute Being.
