The song’s meaning:
Starting, so many times have taken births,
still mind refuses to stop.
In a creation, have seen only forests and wood,
In a creation, have seen only himalayas and snow, mountain after mountains and only rocks.
This illusory world,
Universe expanding only with the imagination of the mind.
Enough o mind,
Prepare yourself for Mahasamadhi without any iota of imagination in the mind (vikalp).
