This is a song sung by Bhaktivinoda Ṭhākura. He's asking everyone to rise early in the morning. Vibhāvarī śeṣa, the night is over, āloka-praveśa, the glimpses of sunlight are there, now you get up. Nidrā chāri uṭha jīva, don't sleep any more. That is the Vedic life. One should not sleep after sunrise. He must rise before sunrise. That is healthy life also. So just instantly after rising from the bed, one should chant the holy names of the Lord. Here it is suggested, bolo hari hari, now you chant Hare Kṛṣṇa mantra, mukunda murāri, Kṛṣṇa's different names.
Mukunda means one who gives liberation. Murari, murari means Kṛṣṇa the enemy of the demon of the name Mura. Rāma is another name, celebrated, Rāma, Kṛṣṇa. Hayagrīva, Hayagrīva is another incarnation of Kṛṣṇa. Similarly Nṛsiṁha, Nara-hari, half-lion, half-man, Nṛsiṁha-deva. Vāmana incarnation, nṛsiṁha vāmana, śri-madhusūdana. Madhusūdana, there was a demon Madhu, and Kaiṭabha, they came to swallow up Brahmā after his creation, so they were killed. Therefore Kṛṣṇa's another name is Madhusūdana. Madhusūdana name is found in Bhagavad-gītā in various places. Madhusūdana means the enemy of Madhu. Kṛṣṇa is both friend and enemy. He is actually friend of everyone, but He becomes enemy-like for one who treats Kṛṣṇa as enemy. He is nobody's enemy, but if anyone wants to see Him as enemy, He appears like enemy. That is the absolute. The demons, they want to see Kṛṣṇa as enemy, so accepting the desire of the demons, He appears before him as enemy, kills him, and gives him liberation. That is absolute pastime of Kṛṣṇa, madhusūdana brajendra-nandana śyāma. Actually God has no name, but His names are selected according to His pastime. Just like this Madhusūdana name is given to Him because He killed the Madhu demon.
Similarly, He is known as brajendra-nandana, the son of vraja, vṛndāvana, because He appeared as the son of Yaśodā and Nanda Mahārāja, brajendra-nandana. Śyāma, His bodily hue is blackish, therefore He is called Śyāmasundara. Pūtanā-ghātana, kaiṭabha-śātana, jaya dāśarathi-rāma. So because He killed the demon Pūtanā, His name is pūtanā-ghātana. Ghātana means killer. Kaitabha-śātana, and He is chastiser of all kinds of dangers. Jaya-dāśarathi-rāma. In connection of His killing the Rāvaṇa, He is glorified, jaya dāśarathi. Dāśarathi means: His father name was Dāśaratha, so He is dāśarathi, dāśarathi-rāma. Yaśodā-dulāla govinda-gopāla. Yaśodā-dulāla means pet son of Mother Yaśodā. Govinda-gopāla, and He is cowherds boy, Govinda, giving pleasure to the cow. Vṛndāvana-purandara, the chief of the Vṛndāvana land. He is the center of attraction for everyone in Vṛndāvana. Rāvāṇāntakara gopī-priya-jana, He is very favorable to the gopīs, gopī-priya. Rādhikā-ramaṇa, and He always enjoys the company of Rādhārāṇī, therefore His name is Rādhikā-ramaṇa. Bhuvana-sundara-bara. So He attracted so many gopīs, that means He is attractive to the whole universe. Nobody is more attractive than Kṛṣṇa within this universe, or within anywhere, therefore He is called bhuvana-sundara-bara. Bara means the chief. Rāvāṇāntakara, mākhana-taskara, gopī-jana-vastra-hari.
