Prabhupāda: Then there is process of making the āsana, deerskin, kuśāsana, then cloth. You have to sit down in that āsana. Āsana, dhyāna, dhāraṇā, prāṇ . . . then?
Pradyumna: "The seat should neither be too high nor too low."
Prabhupāda: Yes, everything is there. "It should not be too high nor too low." Then?
Pradyumna: "And should be situated in a sacred place."
Prabhupāda: A sacred place. Just like formerly, those who were practicing yoga, they were going to Gaṅgotri, where the Ganges is coming down, in the Himalaya, in the Haridwar, in a secluded, sacred place. These are the condition, first condition. So where you are getting these condition fulfilled? You cannot practice yoga in a hotel or in a club. That is not possible.
Student (2): How do you decide whether a place is sacred or not?
Pradyumna: How do you decide whether a place is sacred or not? How do you tell?
Revatīnandana: What is a sacred place?
Prabhupāda: Sacred place, generally we take as a lonely place, solitary place. If it is not solitary, it is not sacred.
Student (2): Is sacred the same as solitary?
Prabhupāda: Yes. They used to sit down in the Himalaya where the Ganges is coming. That is a sacred place. If you go simply on the Ganges side on the bank of the Ganges, Yamunā, you will find immediately purified your mind. Immediately. Or on a seaside where there is nobody disturbing. These are sacred places. Then?
Pradyumna: "The yogī should then sit on it very firmly."
Prabhupāda: Then yogī has to sit down very firmly like this. Yes, straight, perpendicularly. Then?
Pradyumna: "And should practice yoga by controlling the mind and the senses."
Prabhupāda: Then he has to practice meditation for controlling the mind and the senses. First of all āsana, place, sacred place; now, āsana, secluded place, alone. That is stated. These are the yogic process.
