"As the clouds arise, pass, become transformed and dissolve in the open sky, so also is it with the passions in the mind of the wise man." n its liberty and intangibility, the mind of the wise man is thus; likened to the sky. As its clarity is unaltered by the changing vicissitudes of the clouds, so his mind is unchanged by the passions and emotions that form, transform, and pass away there according to their laws."
