Do not allow past experiences to be imprinted on your mind. Perform asanas each time with a fresh mind and with a fresh approach. If you are repeating what you did before, you are living in the memory, so you are living in the past. That means you don't want to proceed beyond the experience of the past. Retaining that memory is saying, 'Yesterday I did it like that.' When I ask, 'Is there anything new from what I did yesterday?' then there is progress. Am I going forward or am I going backward? Then you understand how to create dynamism in a static asana.
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. IyengarThrough surrender the aspirant's ego is effaced, and . . . grace . . . pours down upon him like a torrential rain.
B.K.S. IyengarYoga is as old and traditional as civilization, yet it persists in modern society as a means to achieving essential vitality. But yoga demands that we develop not only strength in body but attention and awareness in mind.The yogi knows that the physical body is not only the temple for our soul but the means by which we embark on the inward journey toward the core.
