On Pesach The Door is Opened

"On the first two nights of Pesach the door is opened." [Shulchan Aruch, Orach Chayim 480]

Our Sages state: "That which He does, He commands His children to do." [Shemos Rabbah 30:9, Yerushalmi, Rosh HaShanah 1:3]   Since G-d commands us to open the doors on the nights of Pesach, it is obvious that He does so Himself.

This means that on the nights of Pesach, G-d opens all the doors and portals for each and every Jew [see Pirkei d'Rebbe Elazar ch 32: 'The treasures of Divine dew are opened on this night']. 

No matter what our actions were during the past year, we are then all able to attain the most lofty and rare spiritual heights, in a manner of "Pesach"  and "leaping" infinitely higher than anything we have ever previously attained. [the deeper meaning of the word "pesach" is 'to leap over']
