Sexual activity, and the thoughts and fantasies of sex, use up a great portion of our vital force. When that force is conserved through abstinence, it becomes sublimated as spiritual energy.

There is always a light within us that is free from all sorrow and grief, no matter how much we may be experiencing suffering.

Everything is sorrow for the wise.

The obstacles that distract thought are disease, apathy, doubt, carelessness, indolence, dissipation, false vision, failure to attain a firm basis in yoga, and restlessness.

Peace can be reached through meditation on the knowledge which dreams give. Peace can also be reached through concentration upon that which is dearest to the heart.

Yoga is the settling of the mind into silence. When the mind has settled, we are established in our essential nature, which is unbounded Consciousness. Our essential nature is usually overshadowed by the activity of the mind.

Just as the pure crystal takes color from the object which is nearest to it, so the mind, when it is cleared of thought-waves, achieves sameness or identity with the object of its concentration.
