A student is to be considered perfected when he understands the identity of the holy name and the Supreme Lord. Unless one is under the shelter of a realized spiritual master, his understanding of the Supreme is simply foolishness. However, one can fully understand the transcendental Lord by service and devotion. When Lord Caitanya offenselessly chanted the Hare Kṛṣṇa mantra, He declared that the mantra could at once deliver a conditioned soul from material contamination. In this age of Kali there is no alternative to chanting this mahā-mantra. It is stated that the essence of all Vedic literature is the chanting of this holy name of Kṛṣṇa: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. Lord Caitanya also told Prakāśānanda Sarasvatī, "In order to convince Me about this essential fact of Vedic knowledge, My spiritual master has taught Me a verse from Bṛhan-nāradīya Purāṇa (38.126). Harer nāma harer nāma harer nāmaiva kevalam/ kalau nāsty eva nāsty eva nāsty eva gatir anyathā: (CC Adi 17.21) In this age of quarrel and hypocrisy, the only means of deliverance is the chanting of the holy name of the Lord. There is no other way. There is no other way. There is no other way."
In three out of the four millenniums (namely Satya-yuga, Tretā-yuga and Dvāpara-yuga) people had the honor to be able to understand transcendence through the path of disciplic succession. However, in the present age, people have no interest in the disciplic succession. Instead, they have invented many paths of logic and argument. This individual attempt to understand the supreme transcendence (called the ascending process) is not approved by the Vedas. The Absolute Truth must descend from the absolute platform. He is not to be understood by the ascending process. The holy name of the Lord—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare—is a transcendental vibration because it comes from the transcendental platform, the supreme abode of Kṛṣṇa. Because there is no difference between Kṛṣṇa and His name, the holy name of Kṛṣṇa is as pure, perfect and liberated as Kṛṣṇa Himself. Academic scholars have no entrance by means of logic and other argument into the understanding of the transcendental nature of the holy name of God. The single path in understanding the transcendental nature of Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare is the chanting of these names with faith and adherence. Such chanting will release one from designated conditions arising from the gross and subtle bodies.
In this age of logic, argument and disagreement, the chanting of Hare Kṛṣṇa is the only means for self-realization. Because this transcendental vibration alone can deliver the conditioned soul, it is considered to be the essence of the Vedānta-sūtra. According to the material conception, there is duality between the name, form, quality, emotions and activities of a person and the person himself, but as far as the transcendental vibration is concerned, there is no such limitation, for it descends from the spiritual world. In the spiritual world there is no difference between the name of the person and the quality of the person. Of course in the material world there is a difference. Because the Māyāvādī philosophers cannot understand this, they cannot utter the transcendental vibration.
