Vimal Teerth is an important teerth and now the Teerth is known as Pishachmochan Talab and is probably the biggest Teerth available in Varanasi. Devotees even now take bath in the Talab (Pond) on auspicious days.
According to Kashi Khand, in ancient times one devotee of Kapardeeshwar named Valmiki was residing nearby. One day a hideous and cruel looking Pishach/demon (ghost) appeared and told Valmiki that he (Pishach) was once residing near the banks of the holy river Godavari and had committed many sins. He learnt that a person who lives in Holy places and commits sins, attains Pishach Yoni and his present appearance was due to his past sins. He appealed to Valmiki to help him.
Valmiki was all the while chanting Shiv Sahasranam(thousand praises of Lord Shiva) and advised the Pishach to take bath in Vimal Kund and pray to Lord Kapardeeshwar. The pishach did as he was told and attained Mukti. After that, Valmiki gave him vibhuti (sacred ash) to be smeared on his forehead and the Pishach followed his instructions. The value of smearing vibhuti on the forehead is amply described in Kashi Khand inasmuch as a person who smears vibhuti in his forhead is safe from untimely death and mishappenings.
After the Pishach attained Mukti, the above Vimal kund came to be called as Pishachmochan Kund (Kashi Khand chapter 54). This huge kund is still existing in the present day and fairly well maintained.
People visit this Pishachmochan Kund for performing Pind Daan (Shraaddh/ rituals for their forefathers). Visiting this place is considered very auspicious during Magh month (January – Feb), Shukla Chaturdasi (one day before Amavasya).
Shri Kamlesh Tiwari is available at the place and he can be contacted on his Cell number (0)9918989066 for doing any special pooja. Shri Tiwari is also available for helping devotees to perform any rituals for their forefathers at Pishachmochan Kund.
