This is one of Swami Sri Yukteswar's favorite songs (from Yogananda's "Cosmic Chants", 1938 edition).
Desire, my great enemy, with his soldiers surrounding me;
Is giving me lots of trouble, oh, my Lord!
That enemy I will deceive, remaining in the castle of peace,
Night and day in Thy joy, oh, my Lord!
What will be my fate? O Lord, tell me!
“Pranayam be thy religion, pranayam will give thee salvation,
Pranayam is the wishing tree.
Pranayam is beloved God,
Pranayam is Creator Lord,
Pranayam is the Cosmic World.
Control the little pranayam, become All-Pervading Pranayam.
You won’t have to fear anything anymore.”
