Uddhava continued: "Balarāma and Kṛṣṇa are the original Personalities of Godhead, from whom the cosmic manifestation emanates. They are chief among all personalities. Each of Them is both the material and the efficient cause of this material creation. Material nature is conducted by the puruṣa incarnations, who all act under Kṛṣṇa and Balarāma. By Their partial representation They enter the hearts of all living entities. They are the source of all knowledge and all forgetfulness also." This is confirmed by Kṛṣṇa in the Bhagavad-gītā, Fifteenth Chapter: “I am present in everyone's heart, and I cause one to remember and forget. I am the original compiler of the Vedānta, and I am the actual knower of the Vedas.” Uddhava continued: "If at the time of death a person can fix his pure mind upon Kṛṣṇa even for a moment, after giving up his material body he becomes eligible to appear in his original, spiritual body, just as the sun rises with all illumination. Passing from his life in this way, he immediately enters into the spiritual kingdom, Vaikuṇṭha."
This is the result of Kṛṣṇa conscious practice. If we practice Kṛṣṇa consciousness in this present body while in a healthy condition and in good mind, simply by chanting the holy mahā-mantra, Hare Kṛṣṇa, we will have every possibility of fixing the mind upon Kṛṣṇa at the time of death. If we do this, then our lives become successful without any doubt. But if we keep our minds always absorbed in fruitive activities for material enjoyment, then naturally at the time of death we shall think of such activities and again be forced to enter material, conditioned bodies to suffer the threefold miseries of material existence. Therefore, to remain always absorbed in Kṛṣṇa consciousness was the standard of the inhabitants of Vṛndāvana, as exhibited by Mahārāja Nanda, Yaśodā and the gopīs. If we can simply follow in their footsteps, even to a minute proportion, our lives will surely become successful, and we shall enter the spiritual kingdom, Vaikuṇṭha.
