In the past, many sādhanas were needed to purify the human mind, body and heart: intense study of the Vedas , extreme austerities, and long periods of meditative absorption. Fortunately for us today, it’s different: the easiest and quickest way to purify ourselves is to chant the Name of God given by the satguru . Simply chanting the Divine Name is enough to end all our suffering. On 8 April, 2020, an extraordinary event took place. On this day, Paramahamsa Vishwananda received the mantra , śrī viṭṭhala giridhāri parabrahmaṇe namaḥ , as it was revealed by Bhagavān Himself. This mantra has now become the mūla-mantra , the main mantra , of the Hari Bhakta Sampradāya. For everyone (whether a devotee or follower or simply curious about the bhakti path) who wants to deepen their spiritual experience, this booklet will help provide a more profound understanding about the nature of this Divine Name in the form of this extraordinary mantra . And now, since we have been graced to receive this Name of Śrī Hari, then the only thing that is needed is our willingness to make it part of our lives, and to chant it throughout our day—no matter what we’re doing—with love.
