Of concentration on the right side of the chest

Whether one should concentrate on the right side of the chest
 or not -

You should not confuse 'concentration on the Heart on the right side of the chest' with 'concentration on the right side of the chest'.

Suppose you are concentrating on a cinema on a screen.
If you concentrate on the cinema, your concentration naturally comes on the screen.
But the converse is not necessarily true.
If you concentrate on the screen, it does not mean you concentrate on the cinema. You would miss the cinema.

The spiritual Heart lies in the right side of the chest.
If you concentrate on the spiritual Heart, your concentration comes naturally on the right side of the chest.

But if you concentrate on the right side of the chest, that does not mean you concentrate on the spiritual Heart.

When devotees had difficulty distinguishing these two, and mistakenly concentrating on the right side of the chest, Bhagavan advised to concentrate on the Heart, which is spiritual, not on the right side of the chest, which is physical.

When your mind becomes quiet, you feel 'I' in the right side of the chest, where the Heart lies.
While your mind is quiet, but not completely quiet, and you still have body-consciousness, you feel 'I' in the right side of the chest.
When your mind becomes even quieter and loses body-consciousness, you do not feel 'I' in relation to the body.

D.: Thoughts cease suddenly, then ‘I-I’ rises up as suddenly and continues. It is only in the feeling and not in the intellect. Can it be right?

M.: It is certainly right. Thoughts must cease and reason disappear for ‘I-I’ to rise up and be felt. Feeling is the prime factor and not reason.

D.: Moreover it is not in the head but in the right side of the chest.

M.: It ought to be so. Because the heart is there.
