Now who can think of Kṛṣṇa always within himself? That is also very easy to understand. If you love somebody, then you can think of him always within yourself. Otherwise it is not possible. If you love somebody, then naturally you'll think of him always. That is described in the Brahma-saṁhitā:
- premāñjana-cchurita-bhakti-vilocanena
- santaḥ sadaiva hṛdayeṣu vilokayanti
- yaṁ śyāmasundaram acintya-guṇa-svarūpaṁ
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
- (Bs. 5.38)
Premāñjana-cchurita-bhakti-vilocanena. One who has developed love of God, or Kṛṣṇa... When I speak of Kṛṣṇa, you should understand "God." Premāñjana-cchurita-bhakti-vilocanena (Bs. 5.38). Another name of Kṛṣṇa is Śyāmasundara. He is blackish like the cloud, but very beautiful; therefore His name is Śyāmasundara. So in this verse of Brahma-saṁhitā it is said that the santaḥ, saintly person, who has developed love for Śyāmasundara, Kṛṣṇa... Premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva (Bs. 5.38). Sadaiva means always, constantly. Santaḥ sadaiva hṛdayeṣu. Hṛdayeṣu means within the heart. Actually, when one comes to the point of samādhi in yoga system, he thinks of Viṣṇu form of the Lord within the heart without any stopping. That is called samādhi. He is absorbed in the thought of Viṣṇu within the heart.
So Kṛṣṇa, Śyāmasundara, is the original Viṣṇu. That is stated in the Bhagavad-gītā. Ahaṁ sarvasya prabhavaḥ (BG 10.8). Sarvasya means including Brahmā, Viṣṇu, Maheśvara. Everyone. Ahaṁ sarvasya prabhavaḥ. So He is the original Viṣṇu. According to śāstra, Vedic literature, He is original Viṣṇu, Kṛṣṇa, then His first expansion is Baladeva. Baladeva expansion: Saṅkarṣaṇa. Saṅkarṣaṇa expansion: Nārāyaṇa. Nārāyaṇa expansion: Viṣṇu, Mahā-Viṣṇu, Garbhodakaśāyī, Kṣīrodakaśāyī. These are statements. So Kṛṣṇa is the original Viṣṇu, Śyāmasundara.
So this is the perfect system. Mad-gatenāntar-ātmanā. "Anyone who is thinking of Kṛṣṇa always within himself, he is first-class yogi." If you want perfection in yoga system, don't be satisfied only by practicing a course of āsana. You have to go further. Actually, the perfection of yoga system means when you are in samādhi, always thinking of the Viṣṇu form of the Lord within your heart, without being disturbed. Therefore the yogis go in a secluded place, and in samādhi they... Controlling all the senses and the mind. You have to control the mind, control the senses, and concentrate everything on the form of Viṣṇu. That is called perfection of yoga. And after that, there are other siddhis, aṣṭa-siddhi-aṇimā, laghimā, prāpti.
So actually this yoga system is very, very difficult. It may be possible by some solitary man, but for the general mass of people it is not possible. The general mass of people, that is recommended in the śāstra that
- harer nāma harer nāma harer nāmaiva kevalam
- kalau nāsty eva nāsty eva nāsty eva gatir anyathā
- (CC Adi 17.21)
There is no other alternative. Nāsty eva, nāsty eva. There is no other alternative, no other alternative, no other alternative. Three times. Three times means yoga, jñāna, and arcana. Yoga system as it was recommended in the Satya-yuga, kṛte yad dhyāyato viṣṇum, that is yoga—always in meditation of Viṣṇu. That is called yoga. Kṛte yad dhyāyato viṣṇuṁ tretāyāṁ yajato makhaiḥ (SB 12.3.52). And in the Tretā-yuga, by performing great sacrifices, yajñas. And in the Dvāpara-yuga, by temple worship. Kalau tad dhari-kīrtanāt: in the Kali-yuga, this age...
