We take up certain practices to purify our mind, but indeed it makes us happy to know there are concrete benefits for yogic practices.
For the one who is firmly rooted in Ahimsa, all enmities cease. We might have heard about the stories of Buddha where even a mad elephant becomes very quiet and peaceful in his presence. When the mind is unshakeably calm with long years of practising non-injury towards others by thought, word and deed and towards oneself, the peace of mind is really solid and palpable. In that presence, none can even fight and even inborn hatred is temporarily stalled.
For the one who has taken the vow of speaking the truth alone and keeping in tune all the time with the presence within and not with the changes outside, their words acquire power. When words are spoken with integrity of body, mind, intellect, and by being totally in the present moment, whatever is said comes true. This is an achievement of practising satya or integrity in speech.
The third quality is asteya or non-stealing. When we do not want to take anything from others that does not belong to us, it means we are content with our own possessions. For such a person who is not expecting any wealth or riches from others’ pockets, all the wealth, jewels and riches of the world will make march past revealing themselves. The more we chase wealth, the farther it runs away from us. It is like chasing our own shadow—though so nearby, it can never be caught. We just need to pause and take a look behind to see our shadow is following us.
When one is rooted in Brahmacharya, the vital energy of the body and mind is saved completely. The common understanding of Brahmacharya is sexual abstinence. The word, when split gives the clear meaning Brahma—the divine self—and charya—to walk the path. Clearly it means, through the roads of the five sense organs, one has to train the mind on the path of God.
When actions are done in this frame of mind that is while seeing it is the divine you see, while hearing, smelling, touching, tasting and thinking you are aware of the divine essence that runs through everything and every thought in the world, then you are rooted in Brahmacharya.
For such people who see the divine in everything, there is an immense gain in prana shakti which is not dissipated in a wrong and illusory understanding of duality.
The store of energy we have is our real wealth. When this is not lost to wasteful seeing, smelling, tasting, touching, hearing, thinking, walking, handling, talking, evacuating and reproducing—that energy is conserved and irrigates the intellect completely.
Such an intellect is very sharp and can easily direct the personality to do only that which is necessary to be done.
