spiritual
Whoever treads the right path under the instruction of a guru who looks after his spiritual welfare, will obtain by his own intuition the accomplishment of his object; know this to be truth.
Whoever attends only to the feeding of his own body, doing no good to others and constantly avoids his own duty and not seeking liberation from the bondage caused by ignorance, kills himself.
He who seeks to know himself while pampering of the body is crossing a river holding onto a crocodile in mistake for a log.
