At the level where the rudra bhaga and top portion meet together, keeping the two sides of
the rudra bhaga as base, the Guru should draw two circles, their diameter being equal to
the height of the top. With the same diameter, he should draw the third circle on the center
of the top. By the conjunction of these three circles, there occur two fish-like designs.
Lines are to be drawn from the face and tail of these fishes. The rounding should commence
from the points where these lines joins the level where the rudra bhaga and the top portion
meet. Such rounding off would be perfect.
