Annie Wood Besant,
An Introduction to Yoga
“ The colour of the mental body of a Master is as moonlight on the rippling ocean. Within that whiteness of moon-like refulgence lie all possibilities of colour, but nothing in the outer world can make the faintest change of hue sweep over its steady radiance. If a change of consciousness occurs within, then the change will send a wave of delicate hues over the mental body which responds only in colour to changes initiated from within and never to changes stimulated from without. His mental body is never His Self, but only His tool or instrument, which He can take up or lay down at His will. ”
