Yoga process is to keep the mind in peaceful condition, tranquility, and then you can concentrate your mind towards the Supreme Absolute. This is yoga process, not a gymnastic, a gymnastic āsana: yāma, niyama, aṣṭāṅga-yoga. Aṣṭāṅga, eight kinds of practices, āsana. Āsana . . . the generally the yogīs come here to show you the āsana, how to sit in different posture. That is mechanical. That is also very nice, how to bring the mind under control. But real business is after your mind is controlled. These processes which generally the yogīs demonstrate, that is the process of controlling the mind. The real meaning of yoga: yoga indriya-saṁyamaḥ. The authorities of yoga practice, they say the yoga practice means to control the senses. That is the yoga practice.

It was spoken by Yamarāja to the servants who went to take Ajāmila to hellish condition of life, and he was saved by the Viṣṇudūta. Because at the end of his life he chanted "Nārāyaṇa." Actually, Nārāyaṇa was his youngest son, and he was very much attached to the little boy. So when Yamadūta in ferocious feature came to take him, he became too much afraid, and because he was accustomed to his son, Nārāyaṇa, so out of fear he chanted very loudly, "Nārāyaṇa, please come. Who are these men?" So simply by chanting "Nārāyaṇa," immediately from Vaikuṇṭha the servants of Nārāyaṇa came, and they saved him from the hands of Yamadūta.
