Science has developed technology such as the wireless that enables instantaneous communication across vast distances with no other external mechanism than a receiver at each end. In Life Divine, Sri Aurobindo says one day science will discover that even the receiver is not necessary, no external mechanism is necessary, for mind has the innate power of direct and instantaneous communication with other minds at any distance.
When one goes to Mother for Pranams, he feels rich, overflowing with joy. Quite often this is felt sometime before and long after the Pranams. This joy is the result of the aspiration of the soul that comes out to meet the Mother of souls. It is a common experience that one flattens out later. Can this joy not be permanent? The answer is yes. Not only that, for one who has taken to this yoga, if this aspiration withdraws, he begins to level off and the past habits begin to re-exercise their hold on him. In the measure one allows this aspiration to die, he reverts to the old life.
