This act signifies the groom's commitment and the bride's acceptance of the marital bond. The ceremony is often accompanied by prayers and blessings from family members, emphasizing the importance of love, fidelity, and prosperity in the couple's life together. Mangalya dharanam is considered a vital part of the wedding, marking the beginning of the couple's journey as partners in life.
