That spiritual and material, what is the difference? The material is dull, and spiritual is consciousness. That is the difference. How the tree gives you . . . a mango tree there gives you a coconut? Because it is conscious. Suppose if I ask from you, because you are a conscious being that, "Give me some coconut," you can give me. "Give me some mango," you can give. But when you are out of this body, then I ask the body, "Give me some milk or cow or . . ." no response. This is material and spiritual. Nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13). So jñānam, real knowledge, is that when we understand that I am spiritual being, I am not this material, and I, my country, that is spiritual world. That is my place. That is jñānam, self-realization. Ātma-darśanam. Ātma-darśanam. Suppose a foreigner is in America, an Indian is in America, or an American is in India, so he is conscious that, "I am American," or "I do not belong to this country." Or Indian, when he goes to America, he knows, "I am Indian. I do not belong to this country." Similarly, when you realize, when you understand that you do not belong to this material world, you belong to the spiritual world, that is self-realization. Ātma-darśanam. That, it is called ātma-darśanam.
Jñānaṁ niḥśreyasārthāya puruṣasya-ātma-darśanam. Puruṣa, puruṣa means enjoyer, and prakṛti means enjoyed. Something is being enjoyed and somebody is enjoyer. That is called prakṛti-puruṣa. So here it is said puruṣa. Puruṣa means the living entity, who is trying to enjoy. He is trying to enjoy. But he is trying to enjoy where? In the material world. Therefore he is not satisfied. In the spiritual world, the puruṣa, the living entity, enjoys with Kṛṣṇa, not alone. Therefore you will find Kṛṣṇa is always accompanied by someone else—either Rādhārāṇī or cowherds boy, or the gopīs, or Mother Yaśodā, or Nanda Mahārāja, or the cows and the calves, like that. Or even with the monkeys.
Kṛṣṇa, you will never find alone. Therefore as soon as we speak "Kṛṣṇa," you must know there are so many associates. Kṛṣṇa . . . just like if I say the president is coming, so one should know the president is not coming alone. He must be accompanied by his secretaries, by his military aide-de-camp, and so many other people, cabinet members. At least one dozen person are coming with him, or with some soldiers, bodyguards. So similarly, when you mean Kṛṣṇa, or God, you should immediately know that He is not alone. He is not impersonal, void. He is full with opulence, full with associates. Therefore this description is of the spiritual world in the Brahma-saṁhitā, Vedic literature, cintāmaṇi-prakara-sadmasu kalpa-vṛkṣa lakṣāvṛteṣu surabhīr abhipālayantam (Bs. 5.29). This is the trees, plants and animals. Then lakṣmī-sahasra-śata-sambhrama-sevyamānaṁ govindam ādi-puruṣaṁ tam ahaṁ . . . He is not only in this surrounding of cintāmaṇi bricks, houses and desire trees, many, many cowherd, not only the cows, surabhi, and the river, but also many thousands of Lakṣmī, goddess of fortune. That is Kṛṣṇa. That is the essence.
