How do we close a vrata (udyāpana)?

on the final day of the vow, do a fuller pūjā, often a small havan, feed people and give dāna — then the vow is complete.

Many vratas are taken for a fixed period: sixteen Mondays, a year of Ekādaśīs, a set number of Satyanārāyaṇa pūjās. Udyāpana is the concluding ceremony that formally completes the vow and offers its fruit to God.

The usual pattern: on the last vrata day, bathe and take a saṅkalpa that you are completing the vow; do the deity’s pūjā more elaborately than usual; perform a small havan if your tradition includes one; read or hear the vrata-kathā; then feed a few brāhmaṇas, girls (kanyās), married women or needy people according to the vrata, and give clothes, food or money as dāna. Many families invite a priest for this day.

If you cannot afford an elaborate udyāpana, a simple pūjā with sincere dāna within your means is accepted. The Dharmasindhu and vrata manuals describe the details for specific vratas.
