There is a veil between the Supermind above and the lower Prakriti below - the veil of ingrained formations. This veil may completely withdraw or be partially withdrawn. Thus even if there is some little opening, with the contact of Light from above the lower nature will get slowly changed.
Even 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.
Safety lies in tending towards our highest and not in resting content with an inferior potentiality..... To rest in or follow after an inferior potentiality may seem safe, rational, comfortable, easy, but it ends badly, in some futility or in a mere circling down the abyss or in a stagnant morass. Our right and natural road is towards the summits.
Outside 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.
There are four great events in history, the siege of Troy, the life and crucifixion of Christ, the exile of Krishna in Brindaban and the colloquy on the field of Kurukshetra. The siege of Troy created Hellas, the exile in Brindaban created devotional religion, (for before there was only meditation and worship), Christ from his cross humanized Europe, the colloquy at Kurukshetra will yet liberate humanity.
Sit in meditation ! But do not think ! Look only at your mind ! You will see thoughts coming into it ! Before they can enter, throw these away from your mind till your mind is capable of entire silence.
What you call the psychic being is the mind of the vital. The heart is the seat of this mind. And this mind is the essence of the senses. It receives things from outside, acts upon things that are outside - knows, gives consent, takes interest in them. But this mind cannot be the Ishwara, but it is the knower, the giver of the consent.
