Mother Mary Sings to Me: To the people who do not kneel during Communion because it is "uncomfortable":
If you are well and able, excuse my bluntness, but get over yourself and kneel. Do you think Jesus was comfortable when they pounded nails through the flesh of his skin and hoisted Him up onto the Cross? NO. He did not even complain. He did it for us. For you! And you’re complaining that kneeling…

While I agree that discomfort is a silly reason not to kneel, no one is required to do so either, and I would hesitate to assign a theological reason for doing so.
Furthermore, we generally kneel before a tabernacle. once we have received Christ, we ARE a tabernacle. The angels are kneeling in adoration around us! Personally, I think it is unnecessary to kneel after communion, since you can’t exactly kneel before yourself. Jesus is inside your very being. I prefer to sit not because of discomfort but because sitting expresses acknowledgement that in that moment Jesus is not something to be adored from the outside, but something within. Also, sitting is the posture to assume when being instructed- and the Eucharist is a lesson in love. Of course, there are good reasons for kneeling as well, and far be it from me to say not to do it, but for many people sitting is the superior posture.
