"The three [dharana, dhyana, and samadhi] together constitute samyama." —Patanjali, Yoga Sutras 3:4
"The word Samyama is used in Yogic literature to denote the triple process of concentration, meditation, and Samadhi practiced at one and the same time." —Swami Sivananda, Practical Lessons in Yoga
"The great yogi Patanjali states in his aphorisms that by practicing a samyama on the physical body, it becomes as light as cotton and can float on air. A samyama consists of three tempos: concentration, meditation and ecstasy. First, the yogi concentrates on his physical body. Second, he meditates on his physical body inducing sleep. Third, full of ecstasy, he gets up from his bed with his body in the Jinn state. Then, he penetrates into hyperspace and escaping from the law of gravity, he floats in the air." —Samael Aun Weor, The Perfect Matrimony
