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.

Hostile Forces

Attacks from adverse forces are inevitable: you have to take them as tests on your way and go courageously through the ordeal. The struggle may be hard, but when you come out of it, you have gained something, you have advanced a step. There is even a necessity for the existence of the hostile forces. They make your determination stronger, your aspiration clearer.

It is true, however, that they exist because you gave them reason to exist. So long as there is something in you which answers to them, their intervention is perfectly legitimate. If nothing in you responded, if they had no hold upon any part of your nature, they would retire and leave you. In any case, they need not stop or hamper your spiritual progress.

Opinions & Judgements

It is the petty ego in each that likes to discover and talk about the (real or unreal) defects of others—and it does not matter whether they are real or unreal. The ego has no right to judge them, because it has not the right view or the right spirit. It is only the calm, disinterested, dispassionate, all-compassionate and all-loving Spirit that can judge and see rightly the strength and the weakness in each being.
Don’t let anything from outside approach and disturb you. What people think, do or say is of little importance. The only thing that counts is your relation with the Divine.

Desire & Impulse

Desire is an impulse: it seizes you, you know, it clings to you, holds you. And then, if you let desire do what it likes, well, it makes you do anything at all, and it makes use of your will. But usually, a desire is something violent, passionate and transient. Rarely is it very sustained; it does not have the stuff, the organisation of a sustained effort. When a desire seizes you, it can make you do anything whatever—but impulsively, not methodically.

Ego

The ego thinks of what it wants and has not. This is its constant preoccupation.
The soul is aware of what it is given and lives in endless gratitude.
…. It is the ego which changes all the contacts of life into suffering, it is the ego which prevents us from being conscious of the Divine Presence within us and from becoming His calm, strong and happy instruments.
Let us make a complete offering of this ego with all its desires to the Divine, let us be confident and wait for the liberation that is sure to come.

Envy, Jealousy & Pride

Jealousy comes from a narrowness of the mind and a weakness of the heart. It is a great pity that so many are attacked by it.
Jealousy and envy are things common to human nature, but these are the very things that a sadhak ought to throw out of himself. Otherwise why is he a sadhak at all? He is supposed to be here for seeking the Divine—but in the seeking for the Divine, jealousy, envy, anger, etc. have no place. They are movements of the ego and can only create obstacles to the union with the Divine.
It is much better to remember that one is seeking for the Divine and make that the whole governing idea and aim of the life. It is that which pleases the Mother more than anything else; these jealousies and envies and competitions for her favour can only displease and distress her.

Vital

It [vital] means prāṇa—it is the life-force and desire-force in a man and the part of the being that responds to desire and is the instrument of the life-forces.
The vital can be a good instrument, but it is a bad master.
The vital has not to be killed or destroyed, but purified and transformed by the psychic and spiritual control.

Anger

Anger is a violent reaction of the vital to some shock that is unpleasant to it; and when it involves words or thoughts, the mind responds to the influence of the vital and also reacts violently. Any expression of anger is the sign of a lack of self-control.
Anger, moreover, like all forms of violence, is always a sign of weakness, impotence and incapacity. Here the deception comes from the approval one gives it or the flattering adjective one covers it with; for rage can be no more than blind, ignorant and asuric—opposed to the light.
