A Verse from Gita

Taken from Gandhi ji's autobiography (Story of My Experiments with Truth) is the following verse from the second chapter of Gita...

If one
Ponders on objects of the sense, there springs
Attraction; from attraction grows desire,
Desire flames to fierce passion, passion breeds
Recklessness; then the memory -- all betrayed --
Lets noble purpose go, and saps the mind,
Till purpose, mind, and man are all undone.
