So kṛṣṇa-praśna, inquiry about Kṛṣṇa, and to understand Kṛṣṇa means on the spiritual platform, ātmavit. That is not material body, material platform. Material platform means "I am this body; you are this body. So Kṛṣṇa is also like us. Kṛṣṇa has a material body, and He is like me." Avajānanti māṁ mūḍhāḥ (BG 9.11). Kṛṣṇa should not be considered as ordinary being. We are worshiping Kṛṣṇa in this temple, not an ordinary being. But Kṛṣṇa is so kind. He is the Supreme Personality of Godhead. Aṇor aṇīyān mahato mahīyān. He is greater than the greatest and still, He can become smaller than the smallest. That is his greatness. He can become... He can show Arjuna the virāḍ-rūpa, the universal form; at the same time, He can talk with Arjuna as ordinary friend. This is Kṛṣṇa. You have read Bhagavad-gītā. He was talking on the chariot as his friend, but when there was need, He... Arjuna wanted to see the universal friend, and Kṛṣṇa showed him that universal form, gigantic form, everything including. So that Kṛṣṇa is ātmā, Paramātmā, and Bhagavān and Brahman. Brahmeti paramātmeti bhagavān iti śabdyate (SB 1.2.11).
So kṛṣṇa-praśna means all-including, everything—past, present, future, moving, not moving, and big and small. This is Kṛṣṇa understanding. Kṛṣṇa understanding means past, present, future, small, large, moving, not moving. This is Kṛṣṇa understanding. But everything is in either of these categories. Everything must be either in the past or at present or in future. So this is past, present and future. And there are moving and... Just like we. We are, animals or man or birds and beasts and insect or aquatics, we are moving. And there are not moving, just like the hill, stones, the trees, plants, the grass. They do not move. But we are moving. So moving, unmoving. And we exist past, present, future. And there is biggest, bigger than the biggest, the whole universe. Although you have got airships, you cannot go, neither others. So many machines have been discovered, but go and see the... They cannot go even to the moon planet, what to speak of others. Therefore it is very big for us. When we speak of universe we cannot think of. They simply calculate, the scientists, by light year, and this year, that year, the speed. But we cannot approach even in this material world, and what to speak of Kṛṣṇa? Kṛṣṇa is in the spiritual world. We cannot calculate the length and breadth of this material world. Our knowledge is so imperfect and meager, and what we can understand of the spiritual world? The material world is a manifestation of Kṛṣṇa's one-fourth energy. And the three-fourths' energy is manifested in the spiritual world. This is the understanding of Kṛṣṇa.
