The basis of waste thoughts is your mind which does not allow you to be manmanabhav.
Since Father Brahma became victorious over having waste thoughts and wasting his time and became karmateet, you have to follow the Father.

You are the creator of your mind and so you control the mind. You are the masters. Because of not having enough controling power it still deceives you.
