Sadho eh tan mithiya jano

This body is a lie, O Seers,
The spirit of God within the only truth.
Why do you wallow in sweet illusions,
Why are you attached to wordly possessions
When nothing will go with thee?
Put away all thoughts of praise or blame,
And fix your mind on His glory.
In every heart dwells the Perfect One,
Says nanak, know him as the Lord.

by Guru Tegh Bahadur
(translation Khushwant Singh)
