The body is the prop for the soul. So why not let the body be propped by a wall or a block?
B.K.S. IyengarIn Savasana or in meditation, the light of the eyes is drawn towards the lotus of the heart, so that the seat of the intelligence of the head is brought into contact with the seat of the intelligence of the heart, which is called the mind. Thus one passes from the individualistic state of consciousness to the universal state of consciousness. It is the merging of the intellect of the brain with the intellect of the soul.
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.
