Scene: A ritual workshop scene: artisans prepare a long, polished wooden balance-beam; sacred threads and water-pot nearby; a clean platform marked for rite.
Purity and integrity matter: even the materials used in dharmic procedures must be sound and untainted.
No tīrtha is referenced; it lists acceptable woods for the balance-beam.
A four-hasta, defect-free, sturdy balance-beam should be made from khadira/arjuna or śiṃśapā/śāla wood.
