תּוֹרָה נב - הַנֵּעוֹר בַּלַּיְלָה

Torah 460

Every person must see to become included in his root [shoresh]. And to become included in his root — he must have bitul [self-nullification]. And it is impossible to come to bitul except through hisbodidus [personal seclusion in prayer]. For through seclusion between himself and his Creator — through this he can nullify everything and cleave to Hashem Yisborach and be included in his root.

The primary time of hisbodidus is at night — when everyone is asleep. And the place must be outside the city — that he goes on a solitary path — that is, in a place where people do not go even during the day. And through this — that he conducts hisbodidus at night on a solitary path as above — he clears his heart and mind from all affairs of this world — and nullifies everything — until he nullifies himself completely. That is: at first he prays much until he nullifies one attribute — and then nullifies another attribute — until he nullifies himself completely — so there is no arrogance and no substance in him at all — until he is in his own eyes as nothing and nothingness literally. Until he merits to come to true bitul. And through this the entire world is included with him in his root — that is, everything is included with him in His unity, may He be blessed.
