cleansing a dirty place of dust, wherein our consciousness is the object in need of purification. This purification takes place largely through the chanting and singing of Radha and Krishna's names. Specifically, the Hare Krishna (mantra) is chanted and sung by practitioners on a daily basis, sometimes for many hours each day. Famously within the tradition, one of Chaitanya Mahaprabhu's close associates, Haridasa Thakur, is reported to have chanted 300,000 holy names of God each day. Diet and lifestyle Gaudiya Vaishnavas follow a lacto vegetarian diet, abstaining from all types of animal flesh, fish and eggs. Onion and garlic are also avoided as they are believed to promote tamasic form of consciousness in the eater. Some Gaudiya Vaishnavas, mainly from ISKCON and Gaudiya Matha, also avoid the intake of caffeine, as they believe it is addictive and an intoxicant. Sampradaya and parampara A Guru—shishya tradition ("lineage") denotes a succession of teachers and disciples within some sampradaya (school, tradition). In accordance with the tradition, Gaudiya Vaishnavism as a subschool belongs to the Brahma Sampradaya, one of the four "orthodox" Vaishnavite schools. Chaitanya Mahaprabhu is said to be a disciple of Isvara Puri who was a disciple of Madhavendra Puri who was a disciple of Lakshmipati Tirtha who was a disciple of Vyasatirtha (1469–1539) of the Madhva Sampradaya. The Gaudiya Vaishnavas call their tradition "Brahma-Madhva-Gaudiya Sampradaya", which originates from Brahma and has Madhvacharya as the original acharya and Chaitanya Mahaprabhu as the acharya-successor. However, this traditional point is at least debatable. Some modern scholars and confessional authors critically assess and pair the Gaudiya Vaishnavism's affiliation with the Madhva tradition. For example, the famous American Indologist and historian of religion Guy L. Beck, with regard to the Chaitanya Sampradaya, notes the following historical events. The first time the Brahma-Madhva affiliation of Gaudiya Vaishnavism was propounded by Baladeva Vidyabhushana was in the 18th century. And to this day, there is no mention of Chaitanya in the annals of the Madhva Sampradaya. For secular scientists this means, originality and non-affiliation of Gaudiya Vaishnavism with other previous branches. At the same time, there is the consensus of scholars, that Chaitanya was initiated by the two gurus of a Vaishnava-oriented group within Adi Shankara's Dashanami order. The Prameya Ratnawali of the above-mentioned gaudiya-acharya Baladeva Vidyabhushana contains the following canonical list of disciplic succession: Krishna, Brahma, Narada, Vyasa, Madhva, Padmanabha, Nrihari, Madhava, Akshobhya, Jayatirtha, Gyanasindhu, Dayanidhi, Vidyanidhi, Rajendra,
