It is not just like a straight line, it is to some extent angular, of angular nature; and where the speed is less – that is, the speed is not the dominating factor – it is a bit circular. Where it is circular in Saḿskrta it is called “kalá” and “kástá”. Otherwise it is angular. The greater the speed, the less will be the angle created by it.

As I have clearly told you last year, microvita are of both positive and negative character; those which are of negative character move in the range of physicality and touch the arena of the psychic world, but they cannot cross the threshold of the psychic world. This is the case with negative microvit
