Through working and serving Hashem much — one merits holy brazenness [azus di-k'dushshah] to speak with the teacher and the Tzadik.

And through speaking with him — one is further aroused to serve Hashem.

It is found that one depends on the other. And likewise there are many matters in the service of Hashem that depend on one another — and one does not know where the beginning is — for each one begins from the other.
