If you are going into frustration and you love it and you enjoy it, then go into it more alert, aware. And enjoy it!
Then don't complain, don't create a contradiction. You love frustration? — love it!
Go into it. Become more artistic about it, decorate it a little more; make new possibilities, new doors to become more frustrated… if you enjoy it.
If you don't enjoy it, then I don't see the problem.
Just go deep into it, watch, and you will find some expectation hidden behind.
Whenever you expect, you are asking for frustration. Drop expectations.
The life of a sannyasin should be a life of no expectations.
And then every moment is such a bliss, such a benediction, because whatsoever God gives is so much.
Then you always feel grateful.
But your desires are so much that whatsoever God gives always looks so little; and you feel frustrated, and you feel complaints, and you cannot feel grateful.
And without gratitude, there is no possibility of prayer arising in your heart. Gratitude is prayer.
