devā ūcuḥ pragr̥hya audumbaraṃ pātraṃ toyapūrṇam udanmukhaḥ | upavāsaṃ tu gr̥hṇīyād yad vā saṃkalpayet vratam |
诸天说道：“当执一只以优昙婆罗木（udumbara）所制之器，盛满清水，面向北方；然后应受持断食之戒（upavāsa），或郑重立下其他誓愿（vrata）。”

Educational Q&A
A vow should be undertaken with deliberate intention (saṅkalpa) and disciplined ritual conduct; fasting is one exemplary form of self-restraint, but any ethically framed observance may be adopted when resolved upon properly.
The gods prescribe a concrete procedure for initiating an observance: the practitioner holds a water-filled udumbara vessel, faces north, and then undertakes fasting or declares another vow, emphasizing formal commitment and ritual alignment.
