Now, when these qualifications are there, then Nārada Muni entrusts Vyāsadeva that, "You can liberate all the conditioned souls." How? Conditioned souls . . . samādhinā anusmara tad-viceṣṭitam: "Simply you try to contemplate, meditate, on the activities of the Supreme Lord." Samādhinā. This is samādhi. Yoga process means to come to the stage of samādhi, aṣṭāṅga-yoga. Yoga means there are eight different stages, and the last stage is called samādhi.
The first stage is yama, saṁyama, controlling the senses. Yoga indriya-saṁyama. The beginning of yoga system means you have to control your senses. This is the first beginning. It is not a plaything, that you do all nonsense and you become a yogī. No. These things are very clearly explained in the Bhagavad-gītā. You have to regulate your life. You have to stop sex life. You have to eat certain procedure. You have to sit under certain procedure. In this way, you have to follow so many regulative principles. That is called yama. And niyama. Niyama means regulative principles. Yama means controlling the senses.
Yama, niyama, then āsana. Then sitting posture. Generally, in these yoga societies in your country, they give some lesson on the sitting posture, and people become captivated that he is practicing yoga. No. First one has to follow regulative principles and control the senses, then practice the sitting postures. Yama, niyama, āsana, prāṇāyāma. And when your sitting posture is correct, then you can exercise breathing. Exercise. Breathing exercise means the nostril which is stopped breathing. You have to press that side and try to breathe from the other side. In this way, breathing exercise. Yama, niyama, āsana, prāṇāyāma. This is called prāṇāyāma.
Then dhāraṇā, meditation. And what is that meditation? That meditation . . . here it is recommended, tad-viceṣṭitam: "meditation on the activities of the Supreme Lord." If the Supreme Lord is impersonal, then where is the question of activities? And how you can concentrate your mind something impersonal? Bhagavad-gītā says that kleśaḥ adhikataras teṣām avyaktāsakta-cetasām (BG 12.5) "Those who are trying to meditate on the impersonal feature, impersonal feature, their process is very troublesome." Kleśo 'dhikataraḥ. Adhikatara means greater.
