Tsan-Dueth Soelkha, also known as Tsan-Dueth Soelkha Drupchen, is a religious festival celebrated in Bhutan. This festival is associated with the practice of Vajrayana Buddhism and involves various rituals and ceremonies. One of the central elements of Tsan-Dueth Soelkha is the Drupchen, which is a specific form of tantric meditation retreat. During the Drupchen, monks engage in intensive meditation, recitation of sacred texts, and ritual practices to invoke blessings and spiritual insights. The festival is a time for the Bhutanese community to come together to participate in these religious activities, seek blessings, and deepen their spiritual connection. Like many Bhutanese festivals, Tsan-Dueth Soelkha may vary in its specific dates from year to year as it follows the Bhutanese lunar calendar.
