Why do we celebrate the death anniversary of sufi saint and not birth anniversary?

The death anniversary of a Sufi saint, often referred to as "Urs," is celebrated because it marks the day the saint is believed to have achieved union with the divine, symbolizing their spiritual journey's culmination. This occasion is seen as a time to honor their teachings, reflect on their legacy, and seek blessings for spiritual growth. Celebrating the Urs emphasizes the enduring impact of the saint's life and message, fostering a sense of community and devotion among followers.
