If you try to understand Kṛṣṇa, that is rāja-vidyā. Rāja-vidyā rāja-guhyaṁ (BG 9.2), most confidential, and pavitram. Pavitram means pure, uncontaminated by this material nature. Our beauty, our strength, our riches, our wisdom—everything what we possess—they are also opulent, but they are limited. Limited, and it will be finished. Finished means as soon as this body is finished, all my opulence, beauty, education, strength—everything—is finished. I begin again, another chapter. This bodily possession, whatever I possessed in this body, as soon as I die, I give up this body, then everything is finished with the body. Therefore in Bhagavad-gītā it is said, mṛtyuḥ sarva-haraś cāham (BG 10.34): "I am death, and I, as death, I take away everything of every person."
That we do not consider that, "I am possessing so many things, but if I do not be engaged in Kṛṣṇa consciousness, everything will be taken at the time of death." That we do not consider; we are so foolish. We are thinking that these things will protect me. No, this will not protect. No. If you become Kṛṣṇa conscious, that will protect you. Not this material possession. It will be taken away. They say: "Can you show me God?" Yes, you will see God. If you are devotee, that you will see God immediately, "Here is God."
