He who has learnt to control his tongue has attained self-control in a great measure. When such a person speaks he will be heard with respect and attention. His words will be remembered, for they will be good and true. When one who is established in truth prays with a pure heart, then things he really needs come to him when they are really needed: he does not have to run after them. The man firmly established in truth gets the fruit of his actions without apparently doing anything. God, the source of all truth, supplies his needs and looks after his welfare.
B.K.S. IyengarThe yogi learns to forget the past and takes no thought for the morrow. He lives in the eternal present.
B.K.S. IyengarHealth begins with firmness in the body, deepens to emotional stability, then leads to intellectual clarity, wisdom and finally the unveiling of the soul.
B.K.S. IyengarDeath is unimportant to a yogi; he does not mind when he is going to die. What happens after death is immaterial to him. He is only concerned with life-with how he can use his life for the betterment of humanity. Having undergone various types of pain in his life and having acquired a certain mastery over pain, he develops compassion to help society and maintains himself in purity and holiness. The yogi has no interest beyond that.
