I sincerely don't agree with this statement.
From my own studies into the esotericism, Islam and Buddhsim it is The our God will come again personified as Jesus, Mahdi and Rigden Jyepo. And the Lord will establish the Kingdom of God on earth. The timespan of this new regime differ and I don't know how long this Empire will last and I dont presume to make a prediction.
In the coming of Shambalah all who do not kneel before Jesus Christ/Rigden Jyepo and swear allegience to God will be purged. Evil will be cleansed with fire, I hope I will live to see the day. But return to God is the only objective in my life. It does give me satisfcation however, knowing that the evil individuals of this world will die and all their mighy plans will fail.
