Śrī Nārada Muni is a naiṣṭhika-brahmacārī. There are four types of brahmacārīs. The first is called sāvitra, which refers to a brahmacārī who, after initiation and the sacred thread ceremony, must observe at least three days of celibacy. The next is called prājāpatya, which refers to a brahmacārī who strictly observes celibacy for at least one year after initiation. The next is called brāhma-brahmacārī, which refers to a brahmacārī who observes celibacy from the time of initiation up to the time of the completion of his study of the Vedic literature. The next stage is called naiṣṭhika, which refers to a brahmacārī who is celibate throughout his whole life. Out of these, the first three are upakurvāṇa, which means that the brahmacārī can marry later, after the brahmacārī period is over. The naiṣṭhika-brahmacārī, however, is completely reluctant to have any sex life; therefore the Kumāras and Nārada are known as naiṣṭhika-brahmacārīs. Such brahmacārīs are called vīra-vrata because their vow of celibacy is as heroic as the vows of the kṣatriyas. The brahmacārī system of life is especially advantageous in that it increases the power of memory and determination. It is specifically mentioned in this connection that because Nārada was a naiṣṭhika-brahmacārī he could remember whatever he heard from his spiritual master and would never forget it. One who can remember everything perpetually is called a śruti-dhara. A śruti-dhara brahmacārī can repeat verbatim all that he has heard, without notes and without reference to books. The great sage Nārada has this qualification, and therefore, having taken instructions from Nārāyaṇa Ṛṣi, he is engaged in propagating the philosophy of devotional service all over the world. Because such great sages can remember everything, they are thoughtful, self-realized and completely fixed in the service of the Lord.
Thus the great sage Nārada, after hearing from his spiritual master Nārāyaṇa Ṛṣi, became completely realized. He became established in the truth, and he became so happy that he offered prayers to Nārāyaṇa Ṛṣi. Nārada Muni addressed Nārāyaṇa Ṛṣi as an incarnation of Kṛṣṇa and specifically addressed Him as the supreme well-wisher of the conditioned souls. It is stated in the Bhagavad-gītā that Lord Kṛṣṇa descends in every millennium just to give protection to His devotees and to annihilate the nondevotees. Nārāyaṇa Ṛṣi, being an incarnation of Kṛṣṇa, is also addressed as the well-wisher of the conditioned souls. As stated in the Bhagavad-gītā, everyone should know that there is no well-wisher like Kṛṣṇa. Everyone should understand that Lord Kṛṣṇa is the supreme well-wisher of everyone and should take shelter of Him. In this way one can become completely confident and satisfied, knowing that he has someone who is able to give him all protection. Kṛṣṇa Himself, His incarnations and His plenary expansions are all supreme well-wishers of the conditioned souls, but Kṛṣṇa is the well-wisher even of the demons, for He gave salvation to all the demons who came to kill Him in Vṛndāvana; therefore Kṛṣṇa’s welfare activities are absolute, for whether He annihilates a demon or gives protection to a devotee, the result of His activities is one and the same. It is said that the demon Pūtanā was elevated to the same position as that of Kṛṣṇa’s mother. When Kṛṣṇa kills a demon, the demon is supremely benefited, as much as a pure devotee is benefited by always being protected by the Lord.
Nārada Muni, after offering respects to Nārāyaṇa Ṛṣi, went to the āśrama of Vyāsadeva, his disciple. Being properly received by Vyāsadeva in his āśrama and seated very comfortably, Nārada Muni narrated the entire story of what he had heard from Nārāyaṇa Ṛṣi. In this way Śukadeva Gosvāmī informed Mahārāja Parīkṣit of the answers to his questions regarding the essence of Vedic knowledge and what is considered to be the ultimate goal in the Vedas. The supreme goal of life is to achieve the transcendental blessings of the Supreme Personality of Godhead and thus become engaged in the loving service of the Lord. One should follow in the footsteps of Śukadeva Gosvāmī and all the other Vaiṣṇavas in the disciplic succession and should pay respectful obeisances unto Lord Kṛṣṇa, the Supreme Personality of Godhead, Hari. The four sects of Vaiṣṇava disciplic succession, namely the Madhva-sampradāya, the Rāmānuja-sampradāya, the Viṣṇu-svāmi-sampradāya and the Nimbārka-sampradāya, in pursuance of all Vedic conclusions, agree that one should surrender unto the Supreme Personality of Godhead.
