We were talking about the Water already, but Laguz rune is not "just" the Water. The Water is a primordial force, that existed before creation. But Laguz comes to the scene only in the middle of the alchemical process. This rune may look simple, but it's very very deep.

In various versions and languages, it means lake, ocean, sea, water, and waterfall.

As you see it has a vertical bar, and it's also a central bar of the Stone.

At the bottom, it starts at the level of Earth, where we already have a Crystal. Like snowy mountain peaks connecting the earth to the sky, the sharp tip of the Crystal pierces the horizon of Emptiness. The beam of Light propagates from the Crystal further upward through the Air and touches the Water.

You may recognize the similarity with the Tiwaz rune because it shares a vertical bar and the right descendant diagonal. It was the north guiding star up there. It was the Night and light from the Water was merely visible through the dark clouds of raw Air.

But now it's daytime and the sky is clear and you feel how soft and friendly the rivulet of Light gently strokes your head, neck, and shoulder from the top left. It's not a distant star anymore, it's a comet, and it brings you not only Water in its descendant diagonal tail but also good news. Your heart may be calm now, the Water is here.

One can recall the legend of Shiva and Ganga. It was dangerous to let the holy waters of the celestial river Ganga fall directly to the earth, as it would cause destruction. Thus, Shiva, represented by the snowy Himalayan peaks, allowed Ganga to fall onto his head and flow down his dreadlocks peacefully.

I suggest using left-hand gesture with index and middle fingers pointing upward, touching the source of Water and the rest of the fingers relaxed naturally, so they are slightly bent and make stairs for Water inviting it to flow down to us. The vertical forearm will play the role of Laguz vertical bar, so align it with your own vertical axis - the spine. You may feel your crystal along the inner side of the forearm up to the wrist. And a beam of golden-white light is going among your fingers along the middle one, warming up your palm from the inside.
