As it is written: “Devekut [bonding] with Hashem is one of the 613 commandments. One is obligated, in accordance to ones ability; to make all efforts to properly observe this mitzva, at all times. One must be bonded with Hashem continually, with great yearning, and with sparks of burning love. There is no greater attribute than this, for all things are included in it. The difficulty in achieving it [devekut] is in direct proportion to its level of importance. The one who sanctifies himself below, is sanctified by above by Hashem, until such a time when that one receives a spirit from above which purifies, and sanctifies him. It is an obligation accordingly with you hability to make all efforts in order to fulfill this mitzva in the appropriate way in all moments” (Rabbi Eliezer Papo, Peleh Yoets, Dalet, Devekut). Now, it is written: והאש על המזבח תוקד בו Ve-haesh al-hamizbeach tukad-bo, “And the fire shall be burning always upon the altar; it shall never go out” (Vayikra 6:5). If we consider this pasuk without the initial vav and hei, I realized that its gematria is 981, the same as for ואתם הדבקים ביהוה אלהיכם חיים כלכם היום Ve’atem ha’devekim baHashem Elokeichem chayim kulchem hayom, “But you who held fast to YKVK are alive every one of you this day” (Devarim 4:4, Vaet’chanan) – possibly the most emblematic verse regarding the mitzva of devekut in the Torah (as well as Devarim 10:20 and 13:5). As such, the fire at the altar is the passion for Hashem that needs to burn constantly in the heart of man. Nothing is more transformational than devekut.
