Caturaśraśyenacit: Square-Shaped Falcon Altar

The image is a minimalist line drawing set against a stark white background. It features a red-outlined cross-like structure composed of five connected squares: one large central square with three smaller squares attached to its left, right, and bottom sides, respectively. The word 'EST' is centered above the top edge of the central square in black sans-serif font.

The image illustrates the 'Caturaśraśyenacit', a specific shape for the Agnicayana (the piling of the fire altar) as prescribed in the Shulba Sutras, the ancient Indian texts concerning the geometric construction of altars for Vedic sacrifice.
