The Mahapitha mandala
Mahapitha doubles Pechaka's cut and inherits a question all even grids share: where is the centre when no single cell sits in the middle? The answer the practice records give is the central two-by-two block — four padas together standing as the Brahma area — with twelve padas ringing them at the edge.
The grid and its centre
Over your plan the tool draws the sixteen padas at your north angle and shades the central block. A tapped point is read by its pada, its position in the ring or the centre, and its direction. Because the Brahma area is a block of four, the result also says how deep inside the block a central point sits — useful when an intrusion only clips a corner of it.
How practitioners use this
Practitioners pick Mahapitha when a plan divides naturally into four bays each way — row housing, square halls, workshops — and when the Brahma question is about an area, not a point: does the stair core overlap the central block at all, and by how much? The block reading gives a measured answer for the client report.
Frequently asked questions
Why is Brahma a block of four here?
Even grids have no middle cell; the practice records assign the central two-by-two as the Brahma area, and the tool follows them.
How does Mahapitha differ from Pechaka?
Pechaka's four padas are the whole grid; Mahapitha's sixteen give an edge ring around a marked centre — a genuinely richer reading.
Which plans suit a four-by-four?
Plans with four natural bays each way, and any brief where the centre must be judged as an area rather than a point.
