Life is life – whether in a cat, or dog or man. There is no difference there between a cat or a man. The idea of difference is a human conception for man’s own advantage.
All thoughts, desires, conventions, attachments which come from outside must be ruthlessly pushed away.
A quiet mind does not mean that there will be no thoughts or mental movements at all, but that these will be on the surface, and you will feel your true being within, separate from them, observing but not carried away.
What comes from outside, one mistakes it as coming from inside. So many thoughts etc. move about outside in the universal – these manifest inside you. All these you must push away as foreign to you and the inside must be made peaceful, calm and quiet; then it will start descending from above.
