The earth and the moon are significant in the way they affect life, but the sun is the source of all energy. Sadhguru tells us: “If the sun’s rays do not fall upon this planet, there is no possibility of life, it’s finished. If the sun disappears right now, in a few hours’ time, everything will turn into solid ice. All the oceans, as well as your blood, will turn into solid ice. Solar energy is fundamental even within your body. Your body is maintaining a certain temperature; the immediate mechanism may be something else but essentially, all that generates heat upon this planet – whether in the form of life or in the form of inanimate material – all of it is solar energy, finding its expression in so many different ways.”

The basis of all spiritual sadhana which is physical in nature is to get us in sync with the cycles of nature. Sadhguru says, “If you are in tune with the cycles of the sun, then physical health, wellbeing, vitality, energy, these things you don’t have to bother about – they are just there with you.”
