Agneepath

A towering verse penned by Sri Harivanshrai Bachchan -

Tu na thakega kabhi, tu na thamega kabhi,
tu na mudega kabhi,
Kar shapath, kar shapath, kar shapath,
Agneepath, Agneepath, Agneepath.

Edited to add meaning as requested -
My literal translation:
You shall not tire ever, you shall not give up ever,
you shall not turn back ever,
take the oath, take the oath, take the oath,
Path of Fire, Path of Fire, Path of Fire

My shallow broad translation:
Swear that you will persevere resolutely, with the test of fire, without ever tiring, without ever giving up, without ever turning back.
