Text of the above letter (slightly edited):
My Dears, The time will come when the whole of this dream will vanish. To everyone of us there must come a time when the whole universe will be found to have been a mere dream, when we shall find that the soul is infinitely better than its surroundings. In this struggle through what we call environments, there will come a time when we shall find that these environments were almost zero in comparison with the power of the soul. It is only a question of time, and time is nothing in the Infinite. It is a drop in the ocean. We can afford to wait and be calm.
(Baba) Sri Sathya Sai Baba
