Rakau = tree
Ra = sun/light kau = to flow Ra = Sacred light u = sustenance
The Ra in Rau means sun or light. So a brief summary of RAKAU is the Streaming of Light or the Flow of Sacred Light.
Behind the physical naming of things there was even a deeper more spiritual meaning. If we look at the leaves of a plant physically we know that plants need sun or light to live. A plant’s leaves draws the light from the sun and turns that light into kai/food. When we look at this from a physical perspective we understand the process using our mind, and its a science.
If we go deeper and look at the process from a spiritual perspective using our heart we will know that the light being transformed into kai is actually divine light illuminated into mātauranga or sacred knowledge.
