How to we get to the tree?

1 Nephi 8:19-20

And I beheld a rod of iron, and it extended along the bank of the river, and led to the tree by which I stood.

And I also beheld a strait and narrow path, which came along by the rod of iron, even to the tree by which I stood; and it also led by the head of the fountain, unto a large and spacious field, as if it had been a world.

1 Nephi 11:25

And it came to pass that I beheld that the rod of iron, which my father had seen, was the word of God, which led to the fountain of living waters, or to the tree of life; which waters are a representation of the love of God; and I also beheld that the tree of life was a representation of the love of God.

NOTE: In the Lord's symbolism:

The "tree of life" represents the "love of God," and
The "fountain of living waters" represents the "love of God."

Thus, the "fountain of living waters" and the "tree of life" are interchangeable symbols.

Also note, it is the "fountain," that is equated to the "tree of life."

Thus, the "fruit" of the tree of life is a symbol which is interchangeable with "living waters".
