The Noam Elimelech in his Sefer MiPeninei Noam Elimelech writes "Performing a Mitzvah is like a salvation for the Shechinah the Divine presence since HaKadosh Baruch Hu is united with His Shechinah through the performance of the commandments".
"Ayin" refers to the sefira of keter, which contains a revelation of the Divine Being completely beyond human perception, just as a crown is above the mind of the wearer. "Ayin" therefore means, "Nothingness," since it transcends human cognition, and can only be accessed through mystical self-annulment. The Baal Shem Tov taught that a person should never pray for his own needs, but only for the fulfillment and redemption of the Shechina, for when the Divine Presence is rectified, so are all of her "limbs", which are the individual components of Creation.
