All this bringing of the mind into a higher state of vibration is included in one word in Yoga — Samadhi. - Swami Vivekananda

Work for work's sake. There are some who are really the salt of the earth in every country and who work for work's sake, who do not care for name, or fame, or even to go to heaven.

God is merciful to those whom He sees struggling heart and soul for realization. But remain idle, without any struggle, and you will see that His grace will never come.

The next step is Asana, posture. A series of exercises, physical and mental, is to be gone through every day, until certain higher states are reached. Therefore it is quite necessary that we should find a posture in which we can remain long. That posture which is the easiest for one should be the one chosen.
