If, in the past, a seeker had received a sacred mantra from a teacher who was not a Vaiṣṇava, it was necessary for them to approach a true Vaiṣṇava guru and, following the proper tradition, receive once again the two principal mantras in the correct way. Regardless of how much knowledge someone might possess—even if they had mastered a thousand branches of the Veda, been initiated into all the great sacrifices, or were born into the most illustrious family—a non-Vaiṣṇava could not be regarded as a true guru. Instead, it was the Vaiṣṇava teacher, who imparted the two mantras properly, who was to be honored as the ācārya—the spiritual preceptor, the one capable of severing the bonds of worldly existence. The twice-born student would take refuge in such an ācārya, dedicating themselves to his service for a year. Only after understanding the student’s character and conduct would the guru then teach the sacred mantra. Before the transmission of the mantra, the guru would perform the necessary purificatory rites, such as tāpa (branding), and then pronounce the mantra. The proper observances of tāpa, puṇḍra (the application of the sacred upright mark), and the giving of a Vaiṣṇava name were all essential. After these rites, the guru would impart the mantra to a disciple whose mind had become pure. The branding with the disc, performed according to the prescribed rules, was known as tāpa. The upright mark was called puṇḍra, and the new Vaiṣṇava name signified the disciple’s spiritual rebirth. With these, and in the correct manner, the guru would then bestow the mantra. The eight-syllabled nyāsa mantra, or another Vaiṣṇava mantra, was to be imparted. Among Vaiṣṇavas, the rite of nyāsa was held as supreme. Therefore, it was declared that, for the Vaiṣṇavas, the rite of nyāsa alone was the highest. A Brāhmaṇa devoted to the knowledge and practice of nyāsa was considered the best among men. There was no mantra higher than nyāsa; this was the truth. Nyāsa was twofold in its nature, and surrender (prapatti) was its alternate form. Only after receiving instruction in both nyāsa and surrender should one undertake any spiritual action; without qualification in both, a person was not fit for all sacred practices. Thus, having studied both, the best among the twice-born should then properly practice the supreme mantra—the glorious eight-syllabled mantra. This eight-syllabled mantra was said to be formed from the praṇava, with the wise recognizing that all mantras begin with this natural praṇava. In every mantra, the praṇava was inherently present, and it was right to prefix all auspicious mantras with it. The syllable "Oṃ" was the praṇava—Brahman itself and the foremost of all mantras. At the beginning of every auspicious mantra, this sacred syllable should be placed. By its very nature, the praṇava was established at the root of the mantra. First came the single syllable "oṃ," then the two syllables "namaḥ," and then followed "nārāyaṇāya"—these five syllables in order. Thus, the eight-syllabled mantra, "oṃ namaḥ nārāyaṇāya," was to be known as the mantra that fulfilled all aims. This mantra dispelled all suffering, was glorious, the very essence of all mantras, and supremely auspicious. Nārāyaṇa was its seer, and the Lord of Śrī (Lakṣmī) was its deity. Its meter was the goddess Gāyatrī, the praṇava its seed, the inseparable goddess its power, and Śrī its mind. The first word was "oṃkāra," the second "namaḥ," and the third "nārāyaṇāya"—thus, the three words were described. The letter "a," the letter "u," and then the letter "m" together formed the praṇava, the very word of Brahman, which was said to be the essence of the three Vedas. By "a," Viṣṇu was indicated; by "u," Śrī was signified; and the letter "m" was said to be their servant, the twenty-fifth principle. By "a," the form of Vāsudeva was declared; by "u," the form of the goddess Śrī was revealed by the sages. By "m," the living being was indicated—the twenty-fifth, distinct from the elements and senses. The elements were represented by the group "ka," the senses by the group "ca," knowledge and the hearts by the group "ṭa" and "ta," the mind by "pa," and ego by "pha." By the letters "ba" and "bha," the great principle prakṛti (nature) was indicated. Yet, the self was that letter "m," the twenty-fifth, distinct from body, senses, mind, and vital airs, conscious and existing as a remainder of the Divine. Some said that the syllable "u" signified determination, and in that view, the essence of Śrī was also expressed by the syllable "va." Just as the radiance of the sun was inseparable from it, so too was Viṣṇu, the ocean of auspicious qualities, denoted by the syllable "a." Viṣṇu was the Lord of Śrī, the universal Self, the supreme seed of the world, the highest Person, creator and sustainer of the universe, ruler, and friend of all beings. The eternal Lady of the worlds, inseparable from Viṣṇu, was the mother of all creation and his beloved consort. Śrī, the foundation of the universe, was indicated by the syllable "ru," and by "ma," the servant of both, the knower of the field, was described. The self was the abode of knowledge, the quality of knowledge, consciousness beyond nature, not inert, changeless, of one form, and possessing its own essence—minute, eternal, all-pervading, of the nature of consciousness and bliss, the sense of "I," imperishable, the field-knower, of diverse forms, and ancient. This self was not subject to burning, destruction, drying, or dissolution; it was imperishable, endowed with its qualities from the beginning, existing as the remainder of the Supreme. By the syllable "ma," the living being, the knower of the field, was always described as subordinate—a servant of Hari alone, never of any other. Thus, only servitude was established for the soul in the middle, and so the meaning of the praṇava was explained. The explanation of the praṇava, together with the rest of the mantra, revealed that the servant of the Supreme had no independence. Therefore, one should remove great ego and pride from the mind; whatever was done by one’s own means was also to be renounced. Ego was represented by the syllable "ma," and its negation by "na"; thus, liberation from ego was achieved by the mind. In this way, the sacred tradition of Vaiṣṇava mantra initiation, the supreme significance of the eight-syllabled mantra, and the profound meaning of the praṇava were revealed—showing the soul’s true nature as the humble servant of the Divine.
