Your own Self-realization is the greatest service you can render the world.

You do not like to suffer yourself. How can you inflict suffering on others?

When there are thoughts, it is distraction: when there are no thoughts, it is meditation.

He whose pure mind turns inward and searches whence does this 'I' arise, knows the Self and merges in You, the Lord, as a river into the sea.

The "I" thought is said to be the sum total of all thoughts. The source of the "I" thought has to be inquired into.

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.

When you truly feel this equal love for all, when your heart has expanded so much that it embraces the whole of creation, you will certainly not feel like giving up this or that. You will simply drop off from secular life as a ripe fruit drops from the branch of a tree. You will feel that the whole world is your home.
