You must purge yourself before finding faults in others. When you see a mistake in somebody else, try to find if you are making the same mistake. This is the way to take judgment and to turn it into improvement. Do not look at others' bodies with envy or with superiority. All people are born with different constitutions. Never compare with others. Each one's capacities are a function of his or her internal strength. Know your capacities and continually improve upon them.
B.K.S. IyengarYoga is an interior penetration leading to integration of being, senses, breath, mind, intelligence, consciousness, and Self. It is definitely an inward journey, evolution through involution, toward the Soul, which in turn desires to emerge and embrace you in its glory.
B.K.S. IyengarOur greed comes from our fear that we will not have enough - whether it is money or love that we grasp. Yoga teaches us to let go of these fears and so to realize the abundance around us and within us.
B.K.S. IyengarThe practice of yogasana for the sake of health, to keep fit, or to maintain flexibility is the external practice of yoga. While this is a legitimate place to begin, it is not the end. Even in simple asanas, one is experiencing the three levels of quest: the external quest, which brings firmness of the body; the internal quest, which brings steadiness of intelligence; and the innermost quest, which brings benevolence of spirit.
