Hayagrīva: Plotinus conceives of the soul as having basically two parts: a lower part, directed toward the body, and a higher part, directed toward the spiritual.
Prabhupāda: Yes. That is, he is prone to fall down because he is very minute quantity, he is small, so there is tendency of falldown. The same example: the small spark of the fire, because it is very small, sometimes it falls down from the fire. So we become, being very small, minute particle of God, we become entangled by this material, external energy. Just like the example: a less intelligent person, in ignorance, commits criminal activities and he goes to jail. He is not supposed to go to the jail, but on account of his little intelligence or ignorance, he commits something which is criminal. This criminality is done by less intelligent class of men. Similarly, persons who are coming into this material world, they are less intelligent. Kṛṣṇa bhuliya jīva bhoga vāñchā kare. They think that they will be able to enjoy life independently, without Kṛṣṇa. This is less intelligence. Just like a very rich man's son, if he thinks that "If I live independently, without being dependent on father," that is his foolishness. How he can become happy independently, living aside from the father? The supreme father is all-opulent, full of everything, and I am minute only. So if I live under the care of the father, naturally I will live very comfortably, like rich man's son. But if I prefer that I shall live independently, that is my foolishness. So only the fools and rascals they try to remain independent of Kṛṣṇa, and they suffer. That is the consequence. And those who are intelligent, even in the, this material life, by association of devotee and spiritual opportunities, when he comes to this understanding, that "I am son of Kṛṣṇa. He claims, ahaṁ bīja-pradaḥ pitā (BG 14.4), 'I am the father,' so I am the son of Kṛṣṇa, and why I am rotting in this way? Let me go back to my father," that is back to home, back to Godhead—that is intelligence. But so long a living entity remains fools and rascal he suffers in this material world. And as soon as he is intelligent enough... That is described in the Caitanya-caritāmṛta, kṛṣṇa ye bhaje sevā (indistinct): anyone who is in Kṛṣṇa consciousness, he is the first-class intelligent man. Without being first-class intelligent man, nobody can come to Kṛṣṇa consciousness. So this training, Kṛṣṇa consciousness, means those who are fortunate, they have come to accept Kṛṣṇa consciousness. This movement is training them how to know perfectly well that he is..., he will be or he is always very, very happy in Kṛṣṇa, not without Kṛṣṇa. That is Kṛṣṇa consciousness movement. When practically we see anyone who has given up this Kṛṣṇa consciousness movement, they are not happy. I don't find anyone. That's fact. They are not happy. They are rotting in degradation. That is their misfortune, less intelligent.
