Psychic Being

The psychic is the spark of the Divine involved here in the individual existence. It grows and evolves in the form of the psychic being—so obviously it cannot have already the powers of the Divine. Only its presence makes it possible for the individual to open to the Divine and grow towards the Divine Consciousness and when it acts it is always in the sense of the Light and the Truth and with the push towards the Divine.

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.
