The method :
Sit comfortably. Withdraw your ears from all sounds and keep them in their functionless state. If there are sounds around you do not get disturbed by them by not thinking about them. Similarly withdraw all your other organs of perception from their respective functions. Enjoy that functionless state of all your organs of sense perception for five minutes.
Still keeping the sense organs in their functionless state withdraw all your organs of actions, mouth, hands, legs, organs of excretion and procreation from their respective actions and keep them in their functionless state. Then enjoy the functionless state of your organs of action for five minutes.
Retaining the functionless state of organs of perceptions and actions still your mind. Free it from its functions of questioning, reasoning, remembering, discriminating, etc. Enjoy the functionless state of your mind for five minutes.
Now keep all the sense organs, organs of action and mind together in the functionless state and enjoy that functionless state. In that state you will observe that there is only one feeling in your awareness, that is 'I'. Be in that "I" feeling alone.
If the mind comes out and goes out to multiple thoughts direct it to only one thought : "I am That I am", or " Who am I?".
When one continues the practice, after sometime the mind will automatically be free from that single feeling also, but without moving to any other.
Then the "I" feeling alone remains. Remain with that 'I" feeling alone for sometime. Don't fix any duration of time and don't even keep the idea of time in your mind.
Then the "I" feeling will also melt and merge, dissolve in the ultimate base, the One, All-pervasive, Eternal, Everpresent, Blissful Consciousness, one's own True Self - the same that one realised through the objective method as well-the very same inexpressible amazing "Experienceless Experience!".
