This is not true. The core objectives of the NKT-IKBU and the Western Shugden Society (WSS) are different. The purpose of the NKT-IKBU is to help pure Kadam Dharma flourish in contemporary society free from politics. The purpose of the WSS is to bring about religious freedom for the millions of Dorje Shugden practitioners who are suffering as a result of the ban implemented by the Dalai Lama.
The NKT-IKBU, a registered charity, is defined as the international union of study and meditation centers that follow the pure tradition of Mahayana Buddhism derived from Atisha and Je Tsongkhapa, introduced to the West by NKT Founder Venerable Geshe Kelsang Gyatso, and that follow the three NKT study programs, and are guided by NKT Internal Rules.
The Western Shugden Society (WSS), a registered company, is defined as an international coalition of practitioners of Dorje Shugden dedicated to accomplishing religious freedom for anyone who wishes to engage in this practice, and to restoring harmony, respect and cooperation between Shugden and non-Shugden Buddhist practitioners around the world.
While differences between the organizations are obvious, there are also areas of overlap. Both the NKT-IKBU and WSS wish for pure Buddhadharma to flourish in this world free from politics. Additionally, both cherish the practice of Dorje Shugden. Many NKT-IKBU practitioners have actively expressed their faith in Dorje Shugden by helping to support and organize the activities of the WSS. They choose to participate as individuals devoted to their practice of Dorje Shugden, not as NKT-IKBU members.
