What is the foundational principle we must be aware of and concentrate on every day?
First, one must be trained in the technique of peace and happiness. These do not depend on the outer, the external or the visible objective world.
So there is no profit in worrying about or debating these matters.
You must take refuge in the Atma (Inner-Self) and the contemplation of the nature of the Atma, that is to say, in the real ‘I’. All this objective world shines only through the glory of the Atma.
The body does not deserve to be identified with the immortal; it is inert matter, and nothing better.
You are not the thing connoted by the word “I”. You are the One, without a second.
The body is subject to change, it is evanescent, and liable to decline. How can it be the Atma?
No, Atma is One and Only. It cannot coexist with another entity. It is only when every spiritual aspirant, and in fact everyone is aware of this, that equality, equanimity, and exhilaration can be established on earth.
Therefore, contemplate on the reality. Leaving aside the seen, concentrate on the seer. That will illumine the truth.
- Prasanthi Vahini, Ch 22.
The Atma is in the body but not of it. The Atma Principle, though active in the body,
does not belong to the body.
