One major derivative of this philosophy is the notion of "devekut", "communion". As God was everywhere, connection with him had to be pursued ceaselessly as well, in all times, places and occasions. Such an experience was in the reach of every person, who only had to negate his inferior impulses and grasp the truth of divine immanence, enabling him to unite with it and attain the state of perfect, selfless bliss. Hasidic masters, well versed in the teachings concerning communion, are supposed not only to gain it themselves, but to guide their flock to it. "Devekut" was not a strictly defined experience; many varieties were described, from the utmost ecstasy of the learned leaders to the common man's more humble yet no less significant emotion during prayer.
