Srila Jiva Gosvami states that the substance of all the Vedic mantras is the chanting of the holy name of the Lord. Every mantra begins with the prefix nama om and eventually addresses by name the Supreme Personality of Godhead. By the supreme will of the Lord there is a specific potency in each and every mantra chanted by great sages like Narada Muni and other rsis. Chanting the holy name of the Lord immediately renovates the transcendental relationship of the living being with the Supreme Lord.

To chant the holy name of the Lord, one need not depend upon other paraphernalia, for one can immediately get all the desired results of connecting or linking with the Supreme Personality of Godhead. It may therefore be questioned why there is a necessity for initiation or further spiritual activities in devotional service for one who engages in the chanting of the holy name of the Lord. The answer is that although it is correct that one who fully engages in chanting the holy name need not depend upon the process of initiation, generally a devotee is addicted to many abominable material habits due to material contamination from his previous life. In order to get quick relief from all these contaminations, it is required that one engage in the worship of the Lord in the temple. The worship of the Deity in the temple is essential to reduce one's restlessness due to the contaminations of conditional life. Thus Narada, in his Pancaratriki-vidhi, and other great sages have sometimes stressed that since every conditioned soul has a bodily concept of life aimed at sense enjoyment, to restrict this sense enjoyment the rules and regulations for worshiping the Deity in the temple are essential. Srila Rupa Gosvami has described that the holy name of the Lord can be chanted by liberated souls, but almost all the souls we have to initiate are conditioned. It is advised that one chant the holy name of the Lord without offenses and according to the regulative principles, yet due to their past bad habits they violate these rules and regulations. Thus the regulative principles for worship of the Deity are also simultaneously essential.
