The return of humankind as a whole to the Kingdom of God is a great Divine action and has been in preparation for thousands of years. After fulfilling their missions on Earth the Masters ascended (in their immortal, heavenly transfigured bodies) to the higher worlds in order to continue their Divine work in Heaven, preparing the place to which humankind is to arise. In almost every spiritual tradition we find prophecies, promises and legends about the work in Heaven of the Masters, or their successors, preparing the event of the Second Coming. For instance, Christ said to his disciples "There are many rooms in my Father's house, and I am going to prepare a place for you. I would not tell you this if it were not so. And after I go and prepare a place for you, I will come back and take you to myself, so that you will be where I am". (John 14: 2-3). In essence, the Second Coming of Christ will conclude His Divine work in Heaven for the final redemption of humankind.
In another great tradition, Buddhism, the Bodhisattva Amoghasiddhi took the torch from the founder of Buddhism, Gautama Buddha, and has been working in Heaven for two thousand five hundred years preparing the new cosmic-spiritual order to be proclaimed by the coming Maitreya Buddha.
In the Kingdom of God everything is interconnected and interlinked in perfect ideal harmony. From the very beginning the Masters have been in Divine contact and after their ascent from the Earth they have been working together in great harmony and collaboration for the salvation of humankind as a whole. We can then speak about the Second Coming of the Masters as a great common action that has been in preparation for thousands of years and will be carried out with love, compassion and harmony, in unity and collaboration.
