उपवीतक्रमेण स्यात्कार्पासं शाणमाविकम् । त्रिवृदूर्ध्ववृतं तच्च भवेदायुर्विवृद्धये
upavītakrameṇa syātkārpāsaṃ śāṇamāvikam | trivṛdūrdhvavṛtaṃ tacca bhavedāyurvivṛddhaye
In the proper order, the upavīta (sacred thread) should be of cotton, then of flax, then of wool. It should be threefold and twisted upward; this is said to increase longevity.
Skanda (deduced: Kāśīkhaṇḍa commonly Skanda → Agastya)
Tirtha: Kāśī
Type: kshetra
Listener: Ṛṣis (frame; not explicit)
Scene: A dvija receives or adjusts a threefold, upward-twisted upavīta; cotton, flax, and wool threads are shown in sequence; a subtle aura suggests ‘āyus-vivṛddhi’.
Sacred symbols are not mere ornament; properly observed saṃskāra forms support disciplined, life-sustaining dharma.
The instruction is part of Kāśī Khaṇḍa’s dharma-teaching milieu connected with Kāśī, without naming a specific tirtha in this verse.
It prescribes the materials and threefold, upward-twisted form of the upavīta.
