The journey of the yogi is one for the brave ones. Its about becoming what is called a bhakta - a faithful one. Moving from fear towards love. From contraction towards expansion.From doubts towards trust.
The yoga tradition says we, as humans exists as a two folded being, we are a sum up of the fundamental energy of the moon and the sun. Which is speaking in codes, Moon = Consciousness/Mind and Sun = Energy/Prana.
