Хасидус к Зехарья 14:8

And this is what our Rabbis of Blessed Memory stated (Berakhot 15a) "Anyone who relieves himself, washes his hands, dons phylacteries, recites Shema, and prays as if he accepts the complete yoke of the kingship of heaven". 'Anyone who relieves himself' and postpones luxuries, this is the aspect of surrender and nullification of the nourishment of the body, for from there are all the luxuries. 'Washes his hands', this is the aspect of נְטִילַת יָדַיִם, washing of the hands, as seen above, via the waters of Da'at/Knowledge. 'Puts on phylacteries', this is the aspect of Da'at and the mentalities that one now merits through the tzaddik, as seen above, {because} he takes Da'at out of the Other Side, etc., as explained above. 'Recites Shema', this is the aspect of rectification of faith which is accomplished through this, as explained above. 'And prays', for now he rectifies prayer completely. For afterwards - after he forces himself to pray in the aspect of Din/Judgment in order to remove Da'at from the Other Side, as explained above - afterwards he rectifies the rectification of prayer like his own rectification, which is the aspect of Mercy and Da'at. This is the essence of the rectification of prayer, as explained above. The essence of prayer is to bring down חֲסָדִים, kindnesses, to arouse the aspect of renewal of the world, the aspect of (Psalms 89:3) "Your steadfast love, חֶסֶד, is confirmed forever". {This is} to awaken the song of Chesed which is greater at that time. This is the aspect of the increase of songs and praises which are said at the time of prayer, as explained above. Then certainly one receives the complete yoke of the kingdom of heaven. For through this the rectification of the renewal of the world is evoked, as explained above. Through this His Kingship and Ruler-ship is revealed completely, etc. The essence of the revelation of His Blessed Kingship will be then, as it is written (Zechariah 14:9) "And Hashem shall be king over all the earth in that day", etc. And it is written (Psalms 97:1) "Hashem is king! Let the earth exult"; "Hashem will reign for ever and ever!" (Exodus 15:18). Therefore there is much to say on the revelation of His Kingship in the future. From there we draw down the acceptance of the complete yoke of the kingship of heaven, right now, in accordance with our service. Everything is for this, to evoke upon us the holiness of the renewal of the world in this world of Action specifically. Through this, everyone will merit according to his portion, to sing, etc. {the song of} the renewal of the world, which is his portion in the World to Come.
