- Statement 1 is correct: The Siddhas (or Sittars) were mystic saints in Tamil Nadu known for their heterodox views. They often critiqued traditional Brahmanical practices, including caste hierarchy and idol worship, emphasizing an inner spiritual path. Many of their teachings can be interpreted as leaning towards monotheism, focusing on the ultimate reality (often Shiva) beyond forms. - Statement 2 is correct: The Lingayats (Virashaivas), founded by Basavanna in the 12th century in the Karnataka region, strongly rejected caste hierarchy and traditional rituals. They questioned the theory of rebirth (samsara) as understood in conventional Hinduism, focusing instead on achieving union with the divine (isto-linga) and transcending the cycle of birth and death in this life.
