Moshes rabbeinu, the first Rebbe, said, I stand between tog and Hashem… And so does every Rebbe. This is how:
1) makes my connection to Hashem stronger:
A) by the Torah he teaches
B) by showing a dugma chaya of living an existence which has no other desires other than what Hashem wants. This is our potential, revealed, and that inspires us to reach that in our own level.
For example, when I see the Rebbe cry over Hashem and his children still remaining in golus, that inspires me to care, and to devote my life to getting us out of golus.
Another example: it can sound like personality suicide to give up everything you want and have no other life then what Hashem wants. By seeing the Rebbe’s living example, u see that such an existence is really who I am, abs far from being a depressing existence, it is the best thing I could ever do for myself. The more I get in touch with the real me, my neshama, the less limited I am by the normal limitations of the world.
Hashem to me:
1) every generation and individual has a specific mission. A tzadik can tell you what Hashem wants you to devote your life to. Which areas you should use your talents. Where your are meant to live etc. Personal guidance from Hashem via the tzadik.
2) a tzadik can bring down brachos from Hashem and tell me where I need to improve in general, and also to make the brachos happen in reality.
Hope this helps.
