Các bậc hiền đức tuyên rằng vùng quanh rốn vươn lên cao gấp đôi một vitasti (một gang tay). Và “trung điểm” được nói là ở ngón giữa, tại chỗ nối giữa đốt giữa và đốt trên của ngón ấy.

Tattva Level: pasha
Shiva Form: Dakṣiṇāmūrti
Role: teaching
It frames the body as a disciplined field for sādhana—precise measures and ‘central points’ support steadiness in worship and yoga, helping the bound soul (paśu) turn toward the Lord (Pati) through ordered practice.
Such measurement language commonly underlies ritual exactness—how one marks, places, and attends to sacred centers—so outer worship of Saguna Shiva (like Liṅga-pūjā) becomes aligned with inner focus and reverence.
A practical takeaway is careful bodily alignment and attention to central points while doing japa (e.g., the Pañcākṣarī) or dhyāna, using traditional measures as aids for steadiness rather than as ends in themselves.
