Letters of Sri Aurobindo
Volume IV - Part 3
No, it is not necessary to lose the mental control; it is best to replace it gradually by the psychic or spiritual. But it happens to many that they lose it before the other is ready or while it is still imperfect and then the Nature-forces act in the physical consciousness which is sometimes held by the descending Peace or Power from above, sometimes by the ordinary Nature-forces. This alternation happens at one stage at least to almost everybody until the higher state prevails.
This over-sensitive brooding on past blows to the vital is an unhealthy sensitiveness. What is past ought not to have a hold like that but be allowed to fade out.
