O my mind, love the Creator/Creation.
With your ears, hear the Glorious Praises of the Source of the Universe,
and with your tongue, sing hymns.
(Pause and consider this teaching)
Join the Saadh Sangat, the company of authentically humble and Holy people
remembering the Beloved One;
even a sinner like you will become pure.
Death is on the prowl, with its mouth wide open, friend.
Today or tomorrow, eventually, Death will seize you.
Wake up and understand this consciously.
Says Nanak, meditate, and resonate with the Beloved One;
this opportunity is slipping away!
