So actually, who is a fallen soul? Fallen soul means anyone who has taken birth in this material world, he is a fallen soul, never mind what he is—he may be Brahmā or he may be an insignificant ant. Anyone who is within this material world . . . because our constitutional position is spirit soul. Spirit means ānandamayo 'bhyāsāt (Vedānta-sūtra 1.1.12), by nature joyful. That is spirit.
So because we have been put into some awkward position of this material existence, therefore we are . . . although constitutionally we are joyful, we do not find anything joyful. Try to understand this point. In this material world, because we have been encaged with this material body, although our endeavor is to become joyful, on account of this encagement of this material body, we are not joyful.
So in the Vedic literature, the whole Vedas, there are four Vedas originally—Sāma, Yajur, Ṛg, Atharva—and from that Vedas, four Vedas, there are so many Upaniṣads, hundred and eight Upaniṣads. And the cream of the Upaniṣads is the Vedānta-sūtra. And the Vedānta-sūtra is very clearly explained by Śrīmad-Bhāgavatam. So this Vedic literature is giving us the help and the clue how we can get out of this miserable condition of life.
This Kṛṣṇa consciousness movement is the essence, or cream, of all these Vedic literature. In the Bhagavad-gītā, you will find that vedaiś ca sarvair aham eva vedyam (BG 15.15): by studying all the Vedic literature, you will have to find out Kṛṣṇa. And Kṛṣṇa is so kind . . . rather Kṛṣṇa's incarnation, Lord Caitanya, is so kind that He is giving you Kṛṣṇa in the form of His name. Nāma rūpe kṛṣṇa avatāra (CC Adi 17.22). So this Kṛṣṇa, Hare Kṛṣṇa movement, practically you can see also, Kṛṣṇa, this name Kṛṣṇa and the original Supreme Personality of Kṛṣṇa is nondifferent. If you simply chant this Hare Kṛṣṇa mantra, then you are associating constantly with Kṛṣṇa. That is a fact.
