Finishing material existence is not all. Just like one man is suffering from fever, and the fever subsides. That is not health. Fever subsides, that's all right. Fever has subsided. But healthy life is when he will work as a healthy man. Simply saying: "No, no more fever," no more fever, lying down on the bed, is the nirvāṇa stage. No more fever. There is no fever, but he is not competent to get up from the bed and work. So that is called nirvāṇa. The fever is finished. That is called nirvāṇa.
So when material existence is finished, that is nirvāṇa. But you have to go farther. You have to develop farther. Then your real, constitutional life as spirit soul will be manifested. So that is bhakti-mārga. That activity is healthy life after nirvāṇa. So those who are in Kṛṣṇa consciousness, they have already passed this material existence and nirvāṇa stage. They are in healthy activities, provided he is actually engaged in Kṛṣṇa consciousness. So ei tina dhāmera haya kṛṣṇa adhīśvara.
