The fact that ancient Ujjain apart from its political and religious importance, enjoyed the reputation of being a great seat of learning as early as the Mahabharata period is borne out by the fact that, Lord Krishna and Sudama received regular instruction in the ashram of Guru Sandipani. The area near the ashram is known as Ankapata, popularly believed to have been the place used by Lord Krishna for washing his writing tablet. The numerals 1 to 100 found on a stone are believed to have been engraved by Guru Sandipani.The Gomti Kunda referred to in the Puranas was the source of water supply to the ashram in the olden days. An image of Nandi, belonging to the Shunga period, is to be found near the tank. The followers of Vallabha sect regard this place as the 73rd seat of the 84 seats of Vallabhacharya where he delivered his discourses throughout India.
