What did Jesus mean by devotees eating His flesh and drinking His blood?

Shri Anil asked: Given below is an excerpt from the Bible (John 6) for reference. 53 So, Jesus said to them, “Truly, truly, I tell you, unless you eat the flesh and drink the blood of the Son of Man, you have no life in you. 54 Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. 55 For My flesh is real food, and My blood is real drink. 56 Whoever eats My flesh and drinks My blood remains in Me, and I in him. 57 Just as the living Father sent Me and I live because of the Father, so also the one who feeds on Me will live because of Me. 58 This is the bread that came down from heaven. Unlike your fathers, who ate the manna and died, the one who eats this bread will live forever.”

Swami relied: The words like flesh, blood and bread only mean the personality of the Human Incarnation. Eating and drinking means loving God-in-human-form to the climax. All these words are symbolic and they convey the concept of true love for God that is proved in practice.
