The navel region is the centre of the vital. It is from here that the movements of the vital rise upward. Above the navel and behind the chest is the centre of the play of emotions and below this takes place the play of the physical. Mulฤdhฤra is the base of the physical. In between the Mulฤdhฤra and the navel, there is another centre of the vital.
Sri AurobindoMetaphysical thinking will always no doubt be a strong element in her mentality, and it is to be hoped that she will never lose her great, her sovereign powers in that direction.
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.
