Chakras
There is [in the Integral Yoga] no willed opening of the chakras, they open of themselves by the descent of the Force. In the Tantrik discipline they open from down upwards, the Muladhara first—in our Yoga, they open from up downward. But the ascent of the force from the Muladhara does take place.
Peace
In the very depths of your being, deep within your breast, the Divine Presence is always there, luminous and peaceful, full of love and wisdom. It is there so that you may unite with it and it may transform you into a luminous and radiant consciousness.
Rest & Relaxation
The rest must not be one which goes down into the inconscience and tamas. The rest must be an ascent into the Light, into perfect Peace, total Silence, a rest which rises up out of the darkness. Then it is true rest, a rest which is an ascent.
Sleep
Sleep can be a very active means of concentration and inner knowledge. Sleep is the school one has to go through, if one knows how to learn his lesson there, so that the inner being may be independent of the physical form, conscious in itself and master of its own life. There are entire parts of the being which need this immobility and semi-consciousness of the outer being, of the body, in order to be able to live their own life, independently.
Calm
Be very careful to remain always calm and peaceful and let an integral equanimity establish itself more and more completely in your being. Do not allow your mind to be too active and to live in a turmoil, do not jump to conclusions from a superficial view of things; always take your time, concentrate and decide only in quietness.
