कālacakra-वर्णनम् तथा āśrama-धarma-निरूपणम्
The Wheel of Time and the Norms of the Āśramas
(त्रीणि धारयते नित्यं कमण्डलुमतन्द्रित: । एकमाचमनार्थाय एकं॑ वै पादधावनम् । एकं शौचविधानार्थमित्येतत् त्रितयं तथा ।॥) वह आलस्य छोड़कर सदा तीन कमण्डलु धारण करे। एक आचमनके लिये, दूसरा पैर धोनेके लिये और तीसरा शौच-सम्पादनके लिये। इस प्रकार कमण्डलु धारणके ये तीन प्रयोजन हैं ।।
Vāyudeva uvāca—trīṇi dhārayate nityaṃ kamaṇḍalum atandritaḥ | ekam ācamana-arthāya, ekaṃ vai pāda-dhāvanam | ekaṃ śauca-vidhāna-artham ity etat tritayaṃ tathā || adhītyādhyāpanaṃ kuryāt tathā yajana-yājane | dānaṃ pratigrahaṃ vāpi ṣaḍ-guṇāṃ vṛttim ācaret ||
风神（Vāyudeva）说道：“人当摒弃懈怠，常持三只水罐（kamaṇḍalu）。一只用于阿遮摩那（ācamana，净化时啜水），一只用于洗足，一只用于处理身之洁净。此即持带水罐之三种用途。又当以婆罗门六业而自立：学习与教授，行祭与为人主祭，施与受（受取供施）。”

Educational Q&A
The verse teaches disciplined daily conduct rooted in purity and duty: maintain practical means for ritual and bodily cleanliness (three kamaṇḍalus for ācamana, foot-washing, and śauca), and follow the sixfold Brahminical obligations—study/teach, sacrifice/officiate, give/accept—so that livelihood and learning remain aligned with dharma.
Vāyudeva is instructing proper dharmic practice, giving concrete rules of conduct and livelihood. The focus is not on battlefield action but on ethical-ritual guidance: how a disciplined person (especially a Brahmin/ascetic) should organize daily life and duties.
