The word Triyugi Narayan is formed of three words tri means three, yugi denotes the period of time - Yuga and Narayan is another name of Vishnu. Pilgrims have been offering wood to the fire in the havana-kund (fireplace) since the three Yugas - hence the place is given the name Triyugi Narayan. Yuga in Hindu philosophy is the name of an epoch or era within a cycle of four ages. The four Yugas are Satya Yuga (1,728,000 human years), Treta Yuga (1,296,000 years), the Dvapara Yuga (864,000 years) and finally Kali Yuga (432,000 years), which is the present Yuga.
