Someone needs to "break the ice" and get this conversation going.
That IS my impression of the Rebbe but with a caveat.
The Rebbe is at one with your own G-dly Soul. As such he is the You of
you, your true Self whose servant is the animal soul. While, depending
on one's understanding or personal "evolution" or journey to one's
toward Tzaddikeit, one will approach at one's level. It is fine to say
please pray in your merit that my cow should give milk and my family
should have the ability to pray and my community may have milk, if
that is your level
Better yet is to ask for spiritual blessings. To do so, search your
soul as if the cause of the cow not giving milk is you and no thing or
person else including the cow. Think that the judgment whether the cow
will give milk is first made above. So what is it in your soul
consistent with the cow not giving milk. Are you not giving? Only you
know the answer, but the real You, the Rebbe, knows better than you if
he is a true Rebbe and has Ruach Kodesh. Start giving more, then go to
the Rebbe.
Tell the Rebbe verbally and with a kvittel that the cow is gnot giving
milk and you believe the heavenly judgment is that you are not giving
the milk of Gemilut Hasadim. Ask for the spiritual blessing that leds
to the physical manifestation. Listen carefully to his answer he may
not agree with you "diagnosis". Follow the Rebbe's advice exactly,
take every possible action to fulfill it, and leave the rest to
HaShem.
Short answer, Yes.
