Until you get a guidance from above you cannot be sure; but to get this guidance it requires time and sadhana.
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 AurobindoDelight is the secret. Learn of pure delight and thou shalt learn of God. What then was the commencement of the whole matter? Existence that multiplied itself for sheer delight of being and plunged into numberless trillions of forms so that it might find itself innumerably.
Sri AurobindoOutside and above the mind there is the play of a consciousness which is lighted by the higher Truth, but man is not conscious of it and of that he has to be conscious.
