Udasi Akhada Prachin Gurdwara Matth belongs to Kalmochan Ghat. It is located on the banks of the Bagmati River in Thapathali. It is believed that Baba Sri Chand, the eldest son of Guru Nanak Dev, stayed in this Matth during his visit to Kathmandu. Even today, the hath likhat (handwritten) Guru Granth Sahib is placed on the first floor of a wooden planked Gurdwara.14 The current Mahant of this Matth is Mahant Pushpadas Udasi.
Inside the Matth, on the extreme right-hand side near the wall of the ghat is a holy water well. On close inspection, one can find the mool mantra inscribed in the stone. Priest Gyani Gurubaksh Singh shares that 250 to 300 years ago, Maharaja Ranjit Singh had sent around 12,000 Sikh soldiers and their horses to Nepal as part of the alliance with Nepal. At that time, the soldiers stayed at the Matth for a brief period of time. If you are lucky, then you might get a glimpse of the hidden treasures placed inside a dark room. In the Matth, large vessels used by the Sikh soldiers to cook are still kept under the safeguard of Mahant Pushpadas Udasi and the guthi.
