According to Lama Zopa Rinpoche:Mantras are effective because they help keep your mind quiet and peaceful, automatically integrating it into one-pointedness. They make your mind receptive to very subtle vibrations and thereby heighten your perception. Their recitation eradicates gross negativities and the true nature of things can then be reflected in your mind’s resulting clarity. By practising a transcendental mantra, you can in fact purify all the defiled energy of your body, speech, and mind.Mantras also serve to focus the mind as a samatha (calming) practice as well as a way to transform the mind through the symbolic meaning of the mantra. In Buddhism, it is important to have the proper intention, focus and faith when practicing mantras, if one does not, they will not work. Unlike in Hinduism, mantras are not believed to have inherent power of their own, and thus without the proper faith, intention and mental focus, they are just mere sounds. Thus according to the Tibetan philosopher Jamgon Ju Mipham:if a mantra is thought to be something ordinary and not seen for what it is, it will not be able to perform its intended function. Mantras are like non-conceptual wish-fulfilling jewels. Infusing one's being with the blessings of mantra, like the form of a moon reflected on a body of water, necessitates the presence of faith and other conditions that set the stage for the spiritual attainments of mantra. Just as the moon's reflection cannot appear without water, mantras cannot function without the presence of faith and other such factors in one's being.Mantras are part of the highest tantric practices in Tibetan Buddhism, such as Deity Yoga and are recited and visualized during tantric sadhanas. Thus, Tsongkhapa says that mantra "protects the mind from ordinary appearances and conceptions". This is because in Tibetan Buddhist Tantric praxis, one must develop a sense that everything is divine.
