Regulate your breathing, and thereby control the mind.
The mind exists in a state of “not enough” and so is always greedy for more. When you are identified with mind, you get bored and restless very easily. Boredom means the mind is hungry for more stimulus…it is not satisfied.
Direct the mind resolutely towards God, restraining the senses in their various seats, and looking on the state of the body as a matter of indifference. Realise your oneness with God, remaining continually intent on identifying with its nature…for what use is there in other, empty things?
Let your aims be common, and your hearts of one accord, and all of you be of one mind, so you may live well together.
Do not be conformed to this world, but be transformed by the renewal of your mind, that you may prove what is the will of God, what is good and acceptable and perfect.
Every portion of body, mind, and spirit yearns for integration of yin and yang… Where ordinary intercourse unites sex organs with sex organs, angelic cultivation unites spirit with spirit, mind with mind, and every cell of one body with every cell of the other body.
“Make your offering,” said the Master. “As you make it be pleased in mind. Make your mind completely calm and contented. Focus and fill the offering-mind with the giving. From this secure position you can be free from ill will.”
