On the top of the head is a Chakra - Sahasradala or the thousand-petalled lotus. There is a Chakra in the middle of the forehead between the eyebrows and one in the heart-centre. The region between the navel and head constitutes the mental field. From navel downward extending till the terminus of the spinal chord, mลซlฤdhฤra, is the seat of the vital.
Sri AurobindoWhat comes from outside, one mistakes it as coming from inside. So many thoughts etc. move about outside in the universal - these manifest inside you. All these you must push away as foreign to you and the inside must be made peaceful, calm and quiet; then it will start descending from above.
Sri AurobindoThus to act under the guidance coming from above, this is one side of the sadhana, the dynamic side. The other one is the discrimination between the Purusha and the Prakriti. The Purusha will calmly observe, give sanction, choose, but will realise that all this does not belong to him - all these are outside him. This is the static side of the sadhana. These two aspects constitute the basis of Yoga.
Sri AurobindoAs often as Herman had witnessed the slaughter of animals and fish, he always had the same thought: in their behaviour toward creatures, all men were Nazis. The smugness with which man could do with other species as he pleased exemplified the most extreme racist theories, the principle that might is right.
Sri Aurobindo
