Rohini Vrat is a recurring vow of fasting and worship kept by Jain devotees, particularly women, on the days when the lunar mansion known as Rohini is in the ascendant. The observance takes its name from this asterism, one of the constellations through which the moon passes in its monthly journey across the sky, and the vow is undertaken on each occasion that the day falls under its influence, so that it returns roughly once in every lunar month across the extended period of the vow.
The vow is traditionally kept over a long duration, undertaken across many months and years until the prescribed number of observances is completed, after which it is brought to a close with a concluding ceremony. This extended commitment gives the vow the character of a sustained discipline rather than a single festival, binding the devotee to a repeated practice of fasting and devotion that unfolds gradually over a great span of time. The observance is associated in tradition with the well-being of the family and the cultivation of the virtues of patience and restraint.
On each day of observance the devotee keeps a fast, which may take the form of complete abstention from food or a more moderate restraint according to capacity, and devotes the day to worship. Temple worship is performed, the images of the Tirthankaras are honoured, and the day is passed in prayer, the recitation of sacred formulas, and reflection. The observance is often connected in particular with the veneration of the Tirthankara Vasupujya, and a traditional narrative recounting the origin and merit of the vow is read in connection with its practice.
The story associated with the vow tells of the fruits of patient endurance and the consequences of conduct across the cycle of rebirths, illustrating through the fortunes of its characters the Jain teaching that present circumstances arise from past actions and that virtue steadily practised bears good fruit. Through the telling of this narrative the observance conveys its moral, encouraging the devotee toward forbearance, devotion and the steady accumulation of merit through disciplined practice.
The vow holds a valued place in the devotional life of many Jain households, particularly among women, who have long been its principal keepers. Its recurring monthly return provides a regular rhythm of fasting and worship woven through ordinary life, and its long duration makes it a sustained act of devotion undertaken over years rather than days. The completion of the full cycle of observances is marked with celebration and the giving of charity, honouring the perseverance that the vow requires.
Rohini Vrat exemplifies a broad category of Jain observances tied to the days and cycles of the calendar, in which the passage of time itself becomes an occasion for recurring devotion. Such vows structure the spiritual life of the household around fixed and repeated practices, cultivating discipline through regularity and binding the devotee to a long-term commitment that deepens with each repetition. In its steady return and its extended duration, Rohini Vrat embodies the Jain conviction that spiritual progress is made not through occasional effort but through the patient and sustained cultivation of restraint, worship and merit across the whole course of life.
