do not believe the rising thoughts that create duality for you

Every night during sleep you let go of your attachment to both the body and the mind, and the result is silence, peace, and an absence of duality. You can have this silence, this peace, and this absence of duality in the waking state by not believing the rising thoughts that create duality for you. Resist limiting thoughts. Replace them with thoughts such as, 'All is myself. Everybody is myself. All animals, all things are myself.' What you think, you become. If you understand and experience that everything is yourself, how can you have likes and dislikes? If everything is you, there will be no desire to avoid anything, no impulse to discriminate in favour of anything.

If you want to discriminate at all, avoid bad company and bad thoughts. At night, when you suddenly start to experience the cold, you pull a blanket over yourself. Pull the blanket of discrimination over yourself when you feel that there is the possibility of bad company and bad thoughts dragging you down.

You may need to do this but the jnani will not because nothing can ever drag him back into the realm of false identifications again. He will always be in that state in which he knows everything to be himself. He will never again have the idea that anything is different or apart from his own Self.
