Swami Mukundananda
Why do I feel sleepy during japa or a spiritual talk but not at a movie?
Why the mind gets lazy in God
The world gives the mind taste and enjoyment, while in the beginning the Divine gives less taste and needs effort. Don't be surprised when the mind goes to the world; do your work and bring it back again.
So the mind becomes lazy. If your mind moves away from God into the world, don't be surprised. Do your work: remove it from the world again.
