Just like in my this life, I can experience. In each stage of my life, I have my past, present and future. You are all young boys. You had your past, as a child, as a boy. Now you are young, and your future is also there as old, as I have become old. So in any stage of life, there is past, present and future. So why not, I am old man, so when I shall die, why there is no future? There must be future. I had my past, I am at present, and there must be future also. The future is that I must get another body. That body may be of animal or trees or demigod or God.
That is stated in the Bhagavad-gītā: yānti deva-vratā devān pitṟn yānti pitṛ-vratāḥ (BG 9.25). You can prepare yourself for your next body. So ultimate goal is to get a body in the kingdom of God. That is—saṁsiddhiṁ paramaṁ gataḥ—that is highest perfection. You can get a body next in . . . as a human being in the rich man's family, or as a king, or as a leader, or as a cat, as a dog, as a tree. That will depend on your work. Similarly, you can get your next body as associates of God, Kṛṣṇa. That is stated, that you can have: mad-yājino 'pi yānti mām (BG 9.25). "Those who are My devotees, they come to Me," Kṛṣṇa says.
