I advise always to read a little at a time, keeping the mind as tranquil as one can, without making an effort to understand, but keeping the head as silent as possible, and letting the force contained in what one reads enter deep within. This force received in the calm and the silence will do its work of light and, if needed, will create in the brain the necessary cells for the understanding. Thus, when one re-reads the same thing some months later, one perceives that the thought expressed has become much more clear and close, and even sometimes altogether familiar.

It is preferable to read regularly, a little every day, and at a fixed hour if possible; this facilitate the brain-receptivity.

Rig Veda 5.10.1, 2, 3, 5, 6

Translation by Sri Aurobindo
Hymns to the Mystic Fire

O Fire, bring to us a light full of energy, O unseizable Ray; for us by thy opulence pervading on every side cut out in our front a path to the plenitude.

O Fire, O Wonderful, come to us with thy will and the growth of the judgment; in thee the sacrificial Friend, achiever of the work can climb to almightiness.

Increase for us, O Fire, the acquisition and the growth of these who are men that are illuminates and by their laudings of thee have attained to the plenitudes of the riches....

These are those flaming rays of thine, O Fire, and they go blazing and violent, like lightnings that run over all quarters, like the voice of a chariot seeking the plenitude.

Soon, O Fire, may alike those of us who are opposed and obstructed attain to protection and the giving of the riches and our illuminates break through all directions and beyond.
