So this bhakti-yoga or any yoga... Real yoga, or the first-class class yoga, is bhakti-yoga. Yoginām api sarveṣāṁ. There are many yogis. Out of them, the bhakta-yogi... Yoginām api sarveṣāṁ mad-gata āntarātmanā (BG 6.47). Without becoming a bhakta-yogi, nobody can think of Kṛṣṇa always. That is not possible. Satataṁ kīrtanyanto māṁ yatantaś ca dṛḍha-vratāḥ. The bhakti-yoga we are teaching in this Kṛṣṇa consciousness movement twenty-four hours' engagement. Superficially we engage from four o'clock in the morning till ten o'clock at night, and that is resting time. But when one is advanced in devotional service, while sleeping he also serves Kṛṣṇa. That means twenty-four hours, satatam. That depends on Because in sleeping you also dream, so what we do during daytime we dream at night. So if one is cent percent engaged in Kṛṣṇa's service, naturally he'll dream also at night. I have seen one of our intimate relative. He was a businessman, selling cloth. So in dream also he was quoting price of cloth. So that is natural. That is not unnatural. Therefore we have to practice. At the time of death, somehow or other, if we quote the price of Kṛṣṇa, then our life are successful. Therefore we should practice: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare. Yaṁ yaṁ vāpi smaran bhāvaṁ tyajaty ante kalevaram (BG 8.6). If we practice Kṛṣṇa, then naturally it is expected that at the time of death we remember Kṛṣṇa. Then immediately we are transferred to the Kṛṣṇaloka, immediately. Tyaktvā dehaṁ punar janma naiti mām eti (BG 4.9). Immediately. There is no doubt about it. Simple thing, but it requires practice.
Therefore, to practice Kṛṣṇa consciousness we have to practice other things. That is the position of sattvaṁ paramaṁ pavitram. That is called śuddha-sattva. Sattvaṁ viśuddhaṁ vāsudeva-śabditam, there is a verse. Pure goodness. Pure goodness means there is only Vasudeva. Vāsudevaḥ sarvam iti (BG 7.19). That is pure sattva, when there is no other conception, simply Vasudeva. Vasudeva is the platform. Just like Vasudeva was the father of Kṛṣṇa. When Kṛṣṇa appeared, Vasudeva was the father. So śuddha-sattva is Vasudeva. Vasudeva means there is no contamination of ignorance or passion, simply sattva-guṇa. Tato rājas tamo bhāvā kāma-lobhādayaś ca ye, ceta etair anāviddham. When your mind and consciousness will not be contaminated by the modes of ignorance and passion, that is śuddha-sattva. That is śuddha-sattva. That is spiritual platform, vasudeva. Then Vasudeva will beget Kṛṣṇa. Sattvaṁ viśuddhaṁ vasudeva-śabditam. So if we purify our existence, another Kṛṣṇa comes or Kṛṣṇa's devotees come. They come in śuddha-sattva. Sattvaṁ paramaṁ pavitram. Then naturally there is śamo damo titikṣa ārjavaṁ jñānaṁ vijñānaṁ āstikyam (BG 18.42). Naturally there is brāhmaṇa behavior. And when one becomes brāhmaṇa, pure, no material contamination, then bhakti appears, after becoming brāhmaṇa or brahma-bhūtaḥ, not material platform. Brahma-bhūtaḥ prasannātmā (BG 18.54). In the material platform, jīva-bhūtaḥ. But in the spiritual platform, brahma-bhūtaḥ.
