The unexpected - just be open to the experience of the Ashram. If you can give of yourself in the spirit of selfless service, then you will naturally receive whatever you need for your spiritual evolution on a deeper level.

"If we expect, then immediately we are defining possible experience within the framework of the ego and its projections. Therefore, as much as is possible, there should be an attitude of child-like simplicity where one is open to the unknown.
Then, and only then, can Yoga help to reveal the hidden treasures which lie within each of us ...
but beyond the confinements of the ego."

Swami Nishchalananda
