First of all, to practice yoga, you have to find out a very secret and sacred place. Yogī yuñjīta satatam ātmānaṁ rahasi sthitaḥ. Rahasi means in a secluded place. Yoga practice cannot be done, haṭha-yoga system, as it is prescribed, aṣṭāṅga-yoga, the eight divisional yoga system, that cannot be practiced in assembly or in a crowded place or in a class. But Bhagavad-gītā says that yogī yuñjīta satatam ātmānaṁ rahasi sthitaḥ. Rahasi sthitaḥ means in a secluded place. Ekākī. Ekākī means alone. Ekākī yata-cittātmā, "controlling the senses and mind." Nirāśīḥ, "without any material desire," aparigrahaḥ, "or taking some help from others." Not that "I shall teach you yoga system by some monetary exchange." This is not yoga system. Aparigrahaḥ. Aparigrahaḥ means one should not expect something from others for learning or manifesting or exhibiting yoga system. Then not only he has to remain alone in a secluded place, but śucau deśe. Śucau deśe means a very sacred place. Pratiṣṭhāpya sthiram āsanam ātmānaḥ. One should have his own sitting place. Not that... That means he cannot change his sitting place. The same sitting place he should continue yoga system. Nāty-ucchritaṁ nāti-nīcaṁ cailājina-kuśottaram. There are skin, deerskins, and then straw mat, and then some soft clothing. In this way there is system of making your āsana, seat.
- tatraikāgraṁ manaḥ kṛtvā
- upaviśyāsane yuñjyād
- yogam ātma-viśuddhaye
"In that seat you have to concentrate your mind in order to purify your senses." That is the process. Real yoga process means to purify the senses and purify the mind. Then how one has to execute that yoga system? It is said, samaṁ kāya-śiro-grīvam. Kāya means this trunk, body, and śira means head, and grīva means the neck. So it should be in a straight line. Samaṁ kāya-śiro-grīvaṁ dhārayann acalam. You should sit in such a posture that it will not move. It will not move. Straight, straight line. Then samprekṣya nāsikāgraṁ svam: "You have to see the tip of your nose, sitting straight line, without any movement, and you have to see the tip of your nose." Samprekṣya nāsikāgraṁ svaṁ diśaś cānavalokayan: "And you cannot see any other side. You have to simply see..." These are the process of concentrating the mind. Then praśāntātmā, by practicing, when you will be completely peaceful. Praśāntātmā vigata-bhīr. Vigata-bhīr means without any fear. And brahmacāri-vrate sthitaḥ, without any sex life. A yogi cannot indulge in sex life. That is the first principle. Brahmacāri-vrata sthitaḥ manaḥ saṁyamya mac-citto: "Concentrate the mind," mac-citto, "focusing the mind upon Me, the Supreme Personality of Godhead." Yukta āsīta mat-paraḥ. This is the yoga practice. But unfortunately, who is practicing yoga in this process? Nobody can find out a secluded place; nobody can concentrate his mind in that way; nobody can fix up in one seat; nobody can constantly look on the tip of the nose.
So there are many other formulas explained here. So therefore, as Lord... And in the Bhāgavata it is stated that kṛte tad dhyāyato viṣṇum: "These processes were tangible or possible to perform in the age which is known as Satya-yuga, or the Golden Age." Now you will find in these Bhagavad-gītā pages that after explaining the process or practice of yoga system, Arjuna said, "My dear Kṛṣṇa, excuse me. I cannot practice it. I cannot practice it. It is impossible for me." Why? "Oh, I am a military man. How can I find out a secluded place? How can I sit in such a way? My mind is always restless. I have to do so many political affairs. So it is not possible for me." So how it is possible for the present-day people, which was refused by Arjuna five thousand years ago? It is not possible. The yoga system is accepted in the Vedic literature, that is a standard practice for self-realization. But the diagnosis of Śrīmad-Bhāgavatam, that kṛte yad dhyāyato viṣṇum (SB 12.3.52), "The yoga system of meditation was possible to be practiced in the Golden Age, or in the Satya-yuga," but not in this age. Then how self-realization is possible? That is said, kalau tad dhari-kīrtanāt: "Simply by chanting this Hare Kṛṣṇa." It doesn't require a secluded place, a sanctified place, or so many rules and regulations. Anywhere you can chant. While you are walking on the street, you can chant Hare Kṛṣṇa. You are in meditation. While you are working, you can chant Hare Kṛṣṇa. Nobody is going to tax you; nobody is going to bother you. You have no loss, but the gain is immense. So this Hare Kṛṣṇa movement is started, and it is easy, it is prescribed. If you at all want to get some spiritual benefit, you try to follow this prescribed method. Just like if you want at all to be cured, you must take the prescription of an experienced physician. Don't take any prescription who is a quack. If you take proper treatment, if you follow the instruction, then you be sure that you get the result out of it.
