Alone

The capacity to be alone is the capacity to love. It may look paradoxical to you, but it's not. It is an existential truth: only those people who are capable of being alone are capable of love, of sharing, of going into the deepest core of another person--without possessing the other, without becoming dependent on the other, without reducing the other to a thing, and without becoming addicted to the other. They allow the other absolute freedom, because they know that if the other leaves, they will be as happy as they are now. Their happiness cannot be taken by the other, because it is not given by the other.

Grace

Ramana says: "Divine grace is essential for realization. It leads one to God realization. But such grace is vouchsafed only to him who is a true devotee or a yogi. It is given only to those who have striven hard and ceaselessly on the path towards freedom."

Happiness

'What is happiness?'

Happiness is the very nature of the Self; happiness and the Self are not different. There is no happiness in any object of the world. We imagine through our ignorance that we derive happiness from objects. When the mind goes out, it experiences misery. In truth, when its desires are fulfilled, it returns to its own place and enjoys the happiness that is the Self. Similarly, in the states of sleep, samadhi and fainting, and when the object desired is obtained or the object disliked is removed, the mind becomes inward-turned, and enjoys pure Self-happiness. Thus the mind moves without rest alternately going out of the Self and returning to it. Under the tree the shade is pleasant; out in the open the heat is scorching. A person who has been going about in the sun feels cool when he reaches the shade. Someone who keeps on going from the shade into the sun and then back into the shade is a fool. A wise man stays permanently in the shade. Similarly, the mind of the one who knows the truth does not leave Brahman. The mind of the ignorant, on the contrary, revolves in the world, feeling miserable, and for a little time returns to Brahman to experience happiness. In fact, what is called the world is only thought. When the world disappears, i.e., when there is no thought, the mind experiences happiness; and when the world appears, it goes through misery.
