Spiritualists have indicated several ways of spiritual training. If they are seriously analysed it would appear that all symbolic worships are nothing but elementary exposition of self-refinement. The object behind all 'Yoga' and 'tap' (asceticism) is to enhance one's own worthiness and sharpness. Worthiness is a magnet which easily attracts useful elements and power.
The basic purpose of spiritual training is enhancement of one's own worthiness. God does not need persuasion or appeasement. God is pleased and showers blessings on the basis of glory which emerges as a result of permeation of idealism in man's personality.
