Ashtavakra says, You who have been bitten by the great black serpent of egoism ‘I am the doer’! Drink the nectar of the faith, ‘I am not the doer’ and be happy. Ashtavakra gives this technique to the king and seeker, Janaka.

Please understand that simply thinking that ‘I am not the doer’ or having faith that ‘I am not the doer’ will not liberate you directly. This technique by itself will not liberate you. It will just make you tired!  You are not able to remember that you are not the doer continuously without a break. The moment you understand that you are not able to remember ‘I am not the doer’ all the time, you will be completely frustrated and you will just drop the mind. The moment you drop the mind, the truth that you are not the doer will simply become reality! That is the technique suggested here.

Unclutching is like a self-purifying method.

This is a very simple understanding of unclutching. All you need to do is remember to unclutch whenever you start giving meaning to old thoughts or whenever you connect with old thoughts and allow them to bother you.
Do not create, maintain or destroy any thought. If you don’t do any of these three things, you are the Supreme Self, Parabrahma!

Unclutching is like a self-purifying method. For any technique to be self-purifying and liberating, the moment you become subtle, the technique should also become subtle, by itself. Unclutching is one such technique. The technique that does not become subtle by itself stays in the gross level. If it is not able to kill itself, if the technique is not able to commit suicide, it will kill you!

The beauty with the technique of unclutching is that it will become subtler and subtler by itself as you become subtler. Finally, it will dissolve.
