An important consequence of following the path of enlightenment is the eventual manifestation of what is known as a Rainbow Body. The rainbow body is merely the outer manifestation of the seven chakras and the associative colours. However, they also appear as signs and portents following on from the death of an adept. If you regularly see vivid rainbows in the sky, accompanied by volcanoes (on TV news reports, for instance) this is a clear indication that an adept (Homoplasmate) has passed on. Other signs which can hail the imminent death of a person, according to the Tibetan Book of the Living and Dying, are investigations and shadows of people being cast upon the morning sky. The Buddhist mantra 'Om Mani Padme Hum' has six syllables, which is therefore considered to be a sacred number. Uttering this mantra whilst meditating on each of the seven chakras/rainbow colors, in turn, produces 42 syllabic iterations in total. 42 is the number of degrees between the primary rainbow and the shadow of the observer. It is also important in terms of the Bardo of Dharmata, further cementing the concept that the Bardo of Dharmata is indeed equivalent to the Chakra System and the Rainbow Body itself.
