This is the first qualification of saintly person or God's servant or God's son. Very tolerant. They have to push on their Kṛṣṇa conscious movement, or God conscious movement, through so many odds. Through so many odds. Because they are just like the child; he's attracted with playthings.
So yoga means, here it is stated, yoga ādhyātmikaḥ puṁsāṁ mato niḥśreyasāya. Yoga system means to lead one to the ultimate benediction. And ādhyātmikaḥ. Ādhyātmikaḥ means "pertaining to the soul." Yoga, practice of yoga, does not mean to gain some material profit. Actually, those who have attained to perfection to some extent in the yoga process . . .
The yoga process which is very much advertised in your country, that is more or less bodily exercise. Yoga process is very difficult for the modern age. I have several times discussed this point.
The preliminary process—yama, niyama, āsana, prāṇāyāma, dhyāna, dhāraṇā, samādhi—the eight processes, to control the senses, to control the mind, to practice sitting postures . . . under certain physical posture the mind become concentrated. So there are different āsanas.
Then meditation, then contemplation, then absorption. These things are preliminary process. But actually, the yoga means to attain ultimate benediction, niḥśreyasāya. What is that niḥśreyasāya? The spiritual realization. That is niḥśreyasāya.
