Lecture by Swami Tattwamayananda. A genius has a natural concentration in one area of specialization. A yogi has control over his concentration. He can concentrate on any topic he chooses. With both, there is effortlessness, but a Yogi has complete alertness and control of his will. A yogi has freedom. In ordinary natural concentration, there is slavery to the object of concentration. The difference comes from the foundation of Yamas, Niyamas, and Vairagya. Dharana and Dhyana can transform our lives through the mastery of the senses. The unit of Dharana, Dhyana, and Samadhi together are called Samyama. Whatever symbol, Pratyaya, we concentrate on is used as a tool to reach the all-pervading transcendental reality. Verse: III.4
