Dakṣiṇāmnāya Śrī Śāradā Pīṭham or Śri Śṛṅgagiri Maṭha is one amongst the four cardinal pīthams following the Daśanāmi Sampradaya - the peetham or matha is said to have been established by acharya Śrī Ādi Śaṅkara to preserve and propagate Sanātana Dharma and Advaita Vedānta, the doctrine of non-dualism.
