Consciousness is indeed always with us. Everyone knows 'I am!' No one can deny his own being.

Concentration is not thinking of one thing. On the contrary, it is excluding all thoughts, since all thoughts obstruct the sense of one's true being. All efforts are to be directed simply to removing the veil of ignorance. Concentrating the mind solely on the Self will lead to happiness or bliss. Drawing in the thoughts, restraining them and preventing them from straying outwards is called detachment (vairagya). Fixing them in the Self is spiritual practice (sadhana). Concentrating on the heart is the same as concentrating on the Self. Heart is another name for Self.

Having set one's family in consonance with the community, he should make his family prosperous to ensure the prosperity of the community.

Nearly all mankind is more or less unhappy because nearly all do not know the true Self. Real happiness abides in Self-knowledge alone. All else is fleeting. To know one's Self is to be blissful always.

There is no mind to control if you realise the self. The mind having vanished, the self shines forth. In the realised man, the mind may be active or inactive, the self remains for him.

Does one require proof of one's own being? Only remain aware of yourself and all else will be known.

Peace is your natural state. It is the mind that obstructs the natural state.
