a prayer offering
Rav Avraham Azulai (Hesed L'Avraham 2:5) explains that the Karbanot in the Beit HaMikdash are able to unify and connect all the lower and upper worlds. The elevation of the Karban, the act itself, would unite and connect the three lower worlds, Beriyah, Yetzirah, and Asiyah, and the intent of the Kohen would unite and connect them all back with the highest world, Atzilut. Without the intent of the Kohen, the light can't flow as it is meant to and the worlds cannot truly benefit from and enjoy the Karban. This is true of both the Ketoret, the incense offering, and the other animal offerings. The only other mitzwah that has this same power to unite and connect all the worlds is Tefillah, prayer, which was instated along the lines of the daily and special musaf offerings.
