One of my favourite passages is from Light on Life by BKS Iyengar.
“As animals, we walk the earth. As bearers of a divine essence, we are among the stars. As human beings, we are caught in the middle, seeking to reconcile the paradox of how to make our way upon earth while striving for something more permanent and more profound. So many seek this greater Truth in the heavens, but it lies much closer than the clouds. It is within us and can be found by anyone on the Inward journey.”
