Within Santal religious life, sacred groves and natural sites are not peripheral settings but the very heart of worship and communal identity. The sacred grove, often called the Jaher or Jaher Than, is understood as the dwelling place of village deities and spirits, the *bonga*, including powerful guardian beings and motherly presences. Trees, rocks, hills, and water sources within and around these groves are regarded as living presences, where the spiritual and material worlds meet. In this way, the landscape itself becomes a kind of temple, not built by human hands but recognized as already inhabited by divine forces.

The Jaher functions as the primary ritual center of the village, distinct from domestic or household worship. Major communal festivals and seasonal ceremonies, such as those linked to agriculture and fertility, are conducted there, often involving processions, offerings, animal sacrifice, and collective feasting. Ritual specialists, such as the village priest, approach the innermost parts of the grove, while the wider community participates in the surrounding rites. These practices affirm the grove as the focal point for communication with deities and spirits, for seeking protection, rain, successful harvests, and safety from misfortune.

Natural sites beyond the grove—hills, rivers, particular trees, and rock formations—also carry deep religious significance. Hills and mountains are seen as dwelling places of powerful spirits and deities, while rivers and other waters serve as sacred spaces for purification and offerings. Specific trees and rocks may mark spiritual boundaries or serve as focal points for ancestor veneration and spirit communication. Through these sites, the Santal religious imagination extends sacred space across the wider environment, so that the village is encircled and permeated by spiritually charged places.

These sacred landscapes also sustain collective memory and a sense of custodianship over the land. Origin stories, migration narratives, and clan histories are often tied to particular hills, rivers, or trees, giving the community a shared spiritual geography. Caring for the grove—keeping it intact, refraining from ordinary cultivation or construction within its core, and maintaining its ritual purity—is treated as a religious duty. By preserving these spaces as relatively undisturbed zones, the community maintains a clear boundary between the sacred and the profane, and safeguards a living meeting ground between humans, nature, and the unseen world.
