Now, as we are accustomed to think either of this material energy or of the spiritual energy, now, how to transfer the thinking? The thinking of the material energy, how it can be transferred into thinking of the spiritual energy?
So for thinking in the spiritual energy the Vedic literatures are there. Just like thinking in the material energies, there are so many literatures—newspapers, magazines, novels, fictions and so many things. Full of literatures.
So our thinkings are absorbed in these literatures. Similarly, if we want to transfer our thinking in the spiritual atmosphere, then we have to transfer our reading capacity to the Vedic literature. The learned sages therefore made so many Vedic literatures, the Purāṇas. The Purāṇas are not stories, they are historical records.
In the Caitanya-caritāmṛta there is a verse which reads as follows: anādi-bahirmukha jīva kṛṣṇa bhuli' gela, ataeva kṛṣṇa veda-purāṇa kailā (CC Madhya 20.117) . . . that these forgetful living entities, conditioned souls, they have forgotten the relationship with the Supreme Lord, and they are engrossed in thinking of the material activities. And just to transfer their thinking power to the spiritual capacity, the Kṛṣṇa-dvaipāyana Vyāsa, he has made so many Vedic literatures.
Vedic literatures means first he divided the Vedas into four. Then he explained them by the Purāṇas. Then for the incapable persons, just like strī, śūdra, vaiśya, he made the Mahābhārata. And in the Mahābhārata he introduced this Bhagavad-gītā. Then again he summarized the whole Vedic literature in the Vedānta-sūtra.
And the Vedānta-sūtra, for future guidance, he made a natural commentation by himself which is called Śrīmad-Bhāgavatam. Śrīmad-Bhāgavatam is called bhāṣyo 'yaṁ brahma-sūtrāṇām (CC Madhya 25.143). It is the natural commentation of Vedānta-sūtra.
So all these literatures, if we transfer our thought, tad-bhāva-bhāvitaḥ, sadā. Sadā tad-bhāva-bhāvitaḥ (BG 8.6). One who is engaged always . . . just like the materialist is always engaged in reading some material literature like newspaper, magazines and fiction, novel, etc., and so many scientific or philosophies, all these things of different degrees of thought—similarly, if we transfer our that reading capacity for these Vedic literatures, as presented by . . . as very kindly presented by Vyāsadeva, then it is quite possible for us to remember at the time of death the Supreme Lord.
That is the only way suggested by the Lord Himself. Not suggested: it is the fact. Nāsty atra saṁśayaḥ (BG 8.5). Undoubtedly. There is no doubt about it. Tasmāt, the Lord suggested, therefore, tasmāt sarveṣu kāleṣu mām anusmara yudhya ca (BG 8.7). He advises Arjuna that mām anusmara yudhya ca. He does not say that "You simply go on remembering Me and give up your present occupational duty." No. That is not suggested. The Lord never suggests something impractical.
