Intuition is the soul within the soul.

Jealousy, in spite of the mad frenzy of its most splendid displays, is a vice of weakness; it arises from a mind whose aspirations and desires are inferior to its accomplishments; it is the child of baulked vanity and failure of courage.

Hate engenders hate. Hate spreads to nations, and from this cause we have devastating wars. In the contemplation of these wars and their origins there is something humiliating to our human race. No Hymn of Hate can ever be a paean of humanity.

Intuition is the soul within the soul.

Jealousy is one of the wickedest of all the passions. It is that which has been the most fruitful mother of tragedies, murders, and wars. But reprehensible though it is, jealousy is almost rather to be pitied than blamed--its first victims are those who harbour the feeling.

To any mental state there corresponds a physical condition.

Every anxiety is a mild form of premonition, and from that point the shade deepens till we get the forebodings and hauntings that merge into lunacy.
