“Thoughts lead to action. Thoughts are the sources of all actions. Thought is the real Karma. Thinking is the real action. If you can root out all evil thoughts in the beginning, you will not do any evil action. If you can nip them in the bud, you will be free from the miseries and tribulations of this world. Watch your thoughts with vigilance and introspection.
Thought is the real action. Activities of the mind are the real Karmas. Once the Vikshepa of the mind vanishes, you will get good Nishtha (meditation). The mind will be very, very calm. Get rid of the impurities of the mind. Have mastery over the mind. Then all the miseries of the Samsara with births and deaths will come to an end. If you free yourself from the clutches of the mind, Moksha (liberation) will come by itself. There is no doubt about this.
A wise man watches his thoughts and eradicates all evil thoughts as they arise from the surface of the mind. So he is happy. He has always pure thoughts. By meditation on God, pure thoughts emanate from the mind, because God is purity (Nitya Suddha).
If you have control over your thoughts, you can turn out immense work with intense concentration. Mental torments of all sorts, cares, worries and anxieties will disappear. The peace that you will enjoy cannot be adequately described.
Those who have even a little control over their thoughts and speech will have a calm, serene, beautiful, charming face, sweet voice and brilliant, lustrous white eyes. Just as sweet perfume continuously emanates from an incense stick, so also divine perfume and divine effulgence (magnetic, Brahmic aura) radiate from a Yogin who has controlled his thoughts and who is constantly dwelling on Brahman or the infinite. The effulgence and perfume of his face is Brahma-Varchas. When you hold in your hand a bouquet made of jasmine, rose and Champaka flowers, the sweet perfume pervades the whole hall and tickles all alike. Even so, the perfume of fame and reputation (Yasas and Kirti) of a Yogin who has controlled his thoughts spreads far and wide. He becomes a cosmic force.
Radium is a rare commodity. There are only 16 grains in the world. Yogins who have controlled their thoughts are also very rare in the world, like radium.”
