[raison d'etre = reason or justification for existence]
The preceptors of spiritual science have propounded the process of self-realisation in such a lucid and systematic manner that if one takes the trouble of acquainting himself with the process, and practises it, he will find no difficulty in integrating and developing his personality.
The doctrine of lesya is not a mere theoretical tenet nor is it pure sophism. It, indeed, is a logical expression of philosophical truth; but it is not a mere persuasive discourse, it is not only theoretically sound but an efficient practical technique for searching and realising the truth. The crux of being religious is to make progress on the path of (internal) change, to go ahead in the direction of transmutation. The advent of taijasa lesya and spiritual progress are synchronous events. In first, the starting point of spiritual progress is transmutation of lesya into taijasa. When taijasa lesya is activated, it produces benign spiritual radiations, and these, in turn, become the catalyst for attitudinal change and personality development.
The entire course of spiritual progress is the process of metamorphosis and it has a pre-set curriculum. Whoever accepts this course positively transmutes his lesya He transcends and transmutes the vicious trinity (of lesya) and enters the realm of the benevolent ones and experiences their beneficial radiations. Under the shelter of the benign trinity, the attitudes get automatically converted. Thus, transmutation is concomitant with behaviour-modification and development of integrated personality. Perception of psychic colours (lesya dhyana) is the means of achieving it.
