While doing sadhana you must quieten your mind and keep awake the Purusha consciousness behind all your activities.
Sri AurobindoEven if the being is not entirely purified, varieties of inspirations and powers may come down from above but this may lead to serious errors. Inspirations from above mixing with the impurities from below get all muddled up and the sadhak takes this for an absolute command. Many a sadhak has thus fallen into danger. Therefore, one must particularly lay stress on the purification of the being.
Sri AurobindoIf it be true that spirit is involved in Matter and apparent Nature is secret God, then the manifestation in the divine in himself and the realization of God within and without are the highest and most legitimate aim possible to man on earth.
Sri AurobindoA quiet mind does not mean that there will be no thoughts or mental movements at all, but that these will be on the surface, and you will feel your true being within, separate from them, observing but not carried away
Sri Aurobindo
