Pure Thirst

I read this Persian saying in Amrita Pritam's 'Seedhi ticket'; thought about it and was really blown away by depth of it.

In desert we sometimes mistake shining sand as water and are fooled, pained and confused by this. The learned and wise are not mistaken and they understand the difference. I say, they don't lack in learning and wisdom but they be lacking in their thirst that is why they do not mistake sand for water; I must be lacking in learning and wisdom and must be a fool but nothing lacks in my thirst!

Deep, isn't it? :-) :D
