How can we know God, since what is limited cannot know what is limitless?

"How can we know God, since what is limited cannot know what is
limitless? Not through our five senses, certainly. We will know
God when we enter his immensity, when we merge with him, when we
become part of him. As long as a drop of water is separate from
the ocean, it cannot know it, but when it returns to the ocean it
can no longer be made separate; it has become the ocean, and it
knows the ocean.
So, as long as human beings remain like separate drops, they
cannot understand the immensity and infinity of God. They have to
merge, fuse with him and become lost in him. This is how they
come to know him, because they become him, they are him. But
until then they will remain outside of God, and they will
continue to wonder about his existence."
