A good effect of the ban is that great Shugden Lamas and Yeshes are spreading the Dharma of Je Tsongkhapa's Lineage far and wide beyond India, the country where most Tibetan refugees had originally settled(and where HH Dalai Lama and CTA are based) . The ban had forced these Lamas and Geshes to leave India and go to the countries which are beyond the long vindictive 'arm' of the CTA. Furthermore, in Tibet, with support from the Chinese Government, the Shugden Lamas and Geshes, who had not left, are now also rigorously spreading the Dharma. Hence the 2600 year teachings of Buddha Shakyamuni , continues in an unbroken Lineage to this day.
Dorje Shugden, the Protector who has unrelentingly promoted Manjushri Je Tsonghapa's lineage of teachings and practice, is himself recognized as an emanation of Wisdom Buddha Manjushri. Thus, this supramundane Protector, in oracles, has also given teachings on the Correct View of Emptiness.It was for this main reason that he arose as a Protector - to protect the teachings of Je Tsongkhpa , in particular, His unexcelled expounding of Narguna's Correct View of Emptiness. Thus the enlightened activities of Buddha Manjushri continues on in Wisdom Protector Dorje Shugden
The sad part of the ban is that a schism has been created between Dorje Shugden practitioners and anti -Shugden pro-Dalai Lama factions. Schism within the Sangha is one of the five most heinous transgressions a Buddhist can commit. Schism is against the grain of what Lord Buddha practiced and taught. Harmony is a pillar of Buddhism. Furthermore, violence and ostracism is being meted out to Shugden practitioners , who are practicing Shugden mainly because it was a practice that their Gurus had conferred on them and because they are following their Guru's instructions, which is the main expression of Guru Devotion. Ostensibly, HH Dalai Lama in giving up and condemning the Shugden practice himself and enforcing a ban on it, is breaking his samaya with his Guru, Kyabje Trijang Rinpoche, who had given him this practice. The result is disharmony, schism, confusion and violence among Buddhists, in place of peace and harmony, which Lord Buddha had always strongly advocated.
