As we celebrate the Rato Machhindranath Jatra, the biggest and longest festival of Patan, it is worth pausing to recognize that this festival is not merely celebration and fanfare, but carries a much deeper meaning, carefully embedded by our ancestors.
The story behind the Jatra goes that saint Gorakhnath once came to the valley seeking alms during planting season. The residents, busy with their work, paid him no attention. Enraged, he meditated and trapped all the nagas of the valley. Since nagas were closely associated with rainfall, the Kathmandu Valley saw no rain for several seasons, leading to famine. To remedy this, the king and a renowned tantric devised a plan to bring Gorakhnath’s own guru, knowing the saint would rise to pay respect, releasing the nagas in the process.
The king, tantric, and a porter traveled to bring Karunamaya, also known as Lokeshwor or Machhindranath. The all-merciful guru, moved by the suffering of the valley’s people, agreed. His essence was transferred into an idol and carried in a chariot procession. Upon seeing his guru, Gorakhnath immediately rose and released the nagas, bringing rain back to the valley. This is why Rato Machhindranath is revered as the god of rain and provider of food.
Woven into this story is one of the most powerful demonstrations of the valley's culture-based water management, or the Hiti system. Though commonly referred to as dhunge-dhara in Nepali, the stone spouts are only one part of a larger network. The Hiti system encompassed state canals (rajkulo), ponds (pokhari), natural aquifers, pipes, and stone spouts, working together to ensure year-round water access, enable groundwater recharge, and reduce urban flooding.
The Jatra itself is deeply tied to this system. Before the chariot procession begins, all major ponds in and around Patan must be filled with water. Since the procession takes place during the dry months, the only way to fill them is through the state canals—meaning their maintenance must be completed every year before the Jatra begins. The procession route, too, reflects this connection. It begins at the strategically located Kamalpokhari of Pulchowk and rests at Purnachandi Pukhu of Gabahal, then at Nuga-Hiti (Sundhara), Langa-Pukhu (Lagankhel), and finally ends near Jawlakhel Hiti and Pukhu.
Each resting point carries ritual significance. At Nuga-Hiti, water from the spout is used in the daily ritual of Lord Machhindranath, as it is at Tangah Hiti, Lagan Hiti, and Jawalakhyo Hiti. In effect, the Jatra cannot proceed unless all Hiti infrastructure is sound and functioning. By embedding water stewardship within religious practice, the festival transforms maintenance from a mundane task into a sacred act of devotion, generating genuine community ownership.
The wisdom embedded in the Jatra goes even further. Beyond annual upkeep, larger maintenance works are needed periodically, and this too is woven into the tradition: every twelve years, major water works are carried out, mirrored by the renewal of the chariot itself, which is built anew and pulled all the way from Bungamati to Lalitpur.
The Jatra also served as a vehicle for intergenerational knowledge transfer. Young people learned where water came from and why it mattered through participation, not textbooks.
Modern urban development in Kathmandu has largely abandoned this integrated approach. Ponds have been filled for construction, underground canals severed by roads, and recharge zones overlooked in land-use planning. Water is now treated as a commodity delivered through pipes, rather than a system sustained by nature and culture together. The consequences are visible: falling groundwater levels and growing dependence on distant, expensive sources.
Learning from our ancestors, Kathmandu must move toward a more sustainable water future. Traditional systems should be recognized not only as heritage monuments but as active components of urban water strategy. Protecting ponds, mapping underground canals, promoting groundwater recharge, and safeguarding aquifers must become integral to development and land-use planning. Equally important, the cultural practices tied to water must be preserved alongside physical restoration—they are the social fabric that ensures long-term care. Recognizing that earlier societies managed scarcity through balance rather than extraction can help reshape the development mindset of today.
As we celebrate the Rato Machhindranath Jatra this year, let us also pause and reflect on the profound wisdom of those who came before us.
