Vigilance

To be vigilant is not merely to resist what pulls you downward, but above all to be alert in order not to lose any opportunity to progress, any opportunity to overcome a weakness, to resist a temptation, any opportunity to learn something, to correct something, to master something. If you are vigilant, you can do in a few days what would otherwise take years. If you are vigilant, you change each circumstance of your life, each action, each movement into an occasion for coming nearer the goal.

Depression

Depression should not be indulged, for all who do the Yoga have difficulties with their ego; but the higher consciousness will always prevail with a true aspiration.
The rule in Yoga is not to let the depression depress you, to stand back from it, observe its cause and remove the cause; for the cause is always in oneself, perhaps a vital defect somewhere, a wrong movement indulged or a petty desire causing a recoil, sometimes by its satisfaction, sometimes by its disappointment. In Yoga a desire satisfied, a false movement given its head produces very often a worse recoil than disappointed desire.
What is needed for you is to live more deeply within, less in the outer vital and mental which is exposed to these touches. The inmost psychic being is not oppressed by them; it stands in its own closeness to the Divine and sees the small surface movements as surface things foreign to the true being.

Death

….death is only a shedding of the body, not a cessation of the personal existence. A man is not dead because he goes into another country and changes his clothes to suit that climate.

Anxiety

With man there has begun this perpetual worrying about what is going to happen, and this worry is the principal, if not the sole cause of his torment. With this objectivising consciousness there has begun anxiety, painful imaginations, worry, torment, anticipation of future catastrophes, with the result that most men—and not the least conscious, the most conscious—live in perpetual torment.

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.
