Swami Sivananda
The real spiritual progress of the aspirant is measured by the extent to which he achieves inner tranquility.
Moral values, and a culture and a religion, maintaining these values are far better than laws and regulations.
A desire arises in the mind. It is satisfied immediately another comes. In the interval which separates two desires a perfect calm reigns in the mind. It is at this moment freed from all thought, love or hate. Complete peace equally reigns between two mental waves.
A mountain is composed of tiny grains of earth. The ocean is made up of tiny drops of water. Even so, life is but an endless series of little details, actions, speeches, and thoughts. And the consequences whether good or bad of even the least of them are far-reaching.
Do not brood over your past mistakes and failures as this will only fill your mind with grief, regret and depression. Do not repeat them in the future.
The harder the struggle, the more glorious the triumph. Self-realization demands very great struggle.
