You know the known, so go a little into the unknown. The mind that is caught up in the known - extended a little beyond reason. The moment you go beyond , you move in the soul. Releasing the bondage of your mind to extend further, reach the unknown a little more. The further you go, you realize that the known is limited and the unknown is vast.
B.K.S. IyengarWhere does the body end and the mind begin? Where does the mind end and the spirit begin? They cannot be divided as they are inter-related and but different aspects of the same all-pervading divine consciousness.
B.K.S. IyengarYes, flexibility of body and physical perfection for Yogasana is important. However more important is the state of your mind, Meditative mind. Your flexibility might be excellent but if your mind is not attentive, you are merely doing some physical exercise, not Yoga.
B.K.S. IyengarIntellectuals tend to be arrogant. Intelligence, like money, is a good servant but a bad master. When practicing pranayama, the yogi [makes] himself humble and without pride in his intellectual attainments.
