With Shar Gaden and Serpom Monasteries growing and developing well, i wonder if it indicates that there will be a separate Shugden lineage which will be an offshoot from the current Gelugpa tradition.
The new incarnations of great masters like Trijang Rinpoche, Domo Geshe Rinpoche and others are already in these monasteries, along with the great Gaden Trisur. As everything is impermanent, it is highly possible that a new school of Buddhism will arise, based on Tsongkhapa's teachings but with Dorje Shugden as the Dharma Protector.
