There are two powers that alone can effect in their conjunction the great and difficult thing which is the aim of our endeavour, a fixed and unfailing aspiration that calls from below and a supreme Grace from above that answers.
But the supreme Grace will act only in the conditions of the Light and the Truth; it will not act in conditions laid upon it by the Falsehood and the Ignorance. For if it were to yield to the demands of the Falsehood, it would defeat its own purpose.
Sri Aurobindo – The Mother with Letters on the Mother: CWSA, Vol. 32, p. 3
The Grace is something that pushes you towards the goal to be attained. Do not try to judge it by your mind, you will not get anywhere, because it is something formidable which is not explained through human words or feelings. When the Grace acts, the result may or may not be pleasant―it takes no account of any human value, it may even be a catastrophe from the ordinary and superficial point of view. But it is always the best for the individual. It is a blow that the Divine sends so that progress may be made by leaps and bounds. The Grace is that which makes you march swiftly towards the realisation.
The Mother – Words of the Mother – II: CWM, Vol. 14, p. 97
It is not indispensable that the Grace should work in a way that the human mind can understand, it generally doesn’t: it works in its own “mysterious” way. At first usually it works behind the veil, preparing things, not manifesting. Afterwards it may manifest, but the sadhak does not understand very well what is happening. Finally, when he is capable of it, he both feels and understands or at least begins to do so. Some feel and understand from the first or very early; but that is not the ordinary case.
Sri Aurobindo – Letters on Yoga – II: CWSA, Vol. 29, p. 171
Who is worthy or unworthy in front of the Divine Grace?
All are children of the one and the same Mother.
Her love is equally spread over all of them.
But to each one She gives according to his nature and receptivity.
The Grace is equally for all. But each one receives it according to his sincerity. It does not depend on outward circumstances but on a sincere aspiration and openness.
The Mother – Words of the Mother – II: CWM, Vol. 14, p. 85
…. There is yet another aspect to the divine grace, the aspect of progress that will be victorious over all obstacles, the aspect that will propel humanity into a new realization, open the doors unto a new world, enable not only a select few to benefit from the divine realization, but through their influence, their example and their power, bring a new and better condition to the rest of humanity.
The Mother – Agenda: Vol. 1, p. 168
In an outburst of heavenly joy and ease
Life yields to the divinity within
And gives the rapture-offering of its all,
And the soul opens to felicity.
A bliss is felt that never can wholly cease,
A sudden mystery of secret Grace
Flowers goldening our earth of red desire.
