Yoga 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. IyengarYou 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. IyengarYou have to get rid of borders, limits, and classifications; then light comes. We see everything on the screen of our ideas. We must get rid of that screen to be able to see what is behind. X's ideas are limited, that is why he remains on the surface. Y got rid of the limits, so she always goes to the depths. We should always meet people and new subjects with no set frame of mind. We have to live like that even after long acquaintance. We must get rid of every set idea to approach everything and everyone with love.
