The initial position of Mahāmudrā: seated with one leg crossed over the opposite thigh (half-lotus position), grasping the foot with both hands.

This configuration seals the energetic circuit of the leg. The practitioner must be “intelligent” (buddhimān) — not just follow instructions mechanically but understand the purpose.

The firm grasp of the big toes creates a direct connection between hands and feet, upper and lower energy circuits. It is the beginning of the sealing.
