Tirukkural 421: Fortress of Wisdom

Wisdom is a weapon to ward off destruction; it is an inner fortress which enemies cannot destroy.

Image of Satguru Sivaya Subramuniyaswami
Your recognition of what is is the way you create it to yourself. This is deep. This is in the realm of contemplation. And only in the realm of contemplation will you begin to conceive of it.
