The source of the thoughts is the ego.+

Thinker, thoughts, and the world in which the thinker exists have nothing to do with the Soul, the Self, which is hidden by ignorance.

Those who think by inquiring to whom the thoughts come, from will not be able to realize the ‘Self’ because they are thinking the ‘Self is within their body. 

The ‘Self’ is not within the body but it is hidden by the universe, which is the dualistic illusion or Maya.

Thoughts and thinker and the world in, which the thinker exists belong to the dualistic illusion. Without form, time, and space the thoughts will not form. 

Thoughts come to the thinker. The thinker is an individual whereas the ‘Self is not an individual.  

The source of the thoughts is the ego. Without the ego, the thoughts will not arise. Thoughts and thinker and the world in which the thinker exists have nothing to do with the Soul, the ‘Self, which is hidden by the dualistic illusion (I).

You are the thinker. The thoughts come to you. You are bound by form, time, and space whereas The Soul, the Self is a formless, timeless, and spaceless existence. 

The thoughts will not rise in the domain of the Soul, the ‘Self’ because it is the ever-formless, timeless, and spaceless existence.

The thoughts come to the thinker within the universe, which is the dualistic illusion or Maya. Without the dualistic illusion or Maya the thinker, thoughts, and the world in which the thinker exists cease to exist.

Just by finding out to whom the thoughts come? Who is the knower? it is impossible to realize the truth, which is beyond form, time, and space. 

A perfect understanding of ‘what is what' is what is very much necessary to cross the threshold of the dualistic illusion. : ~ Santthosh Kumaar
