it means beings come from god in vessels & connect to this world at the feet area of the human. Then they enter into our bodies through the feet area & it is like entering a pyramid that has spiritual power inside. That allows them to see the blue sky of this world through us.
The tree is the tree of God & all beings including ourselves come through the passages in its roots, trunk & branches, inside vessels that keep us safe. The Tree of God has a branch reaching to each person & connecting to their feet. Many people report feeling long spiritual tendrils going inside their feet. The tree connects to our bodies & the spiritual beings come through the tree & enter at our feet & merge with us, & walk through this world with us. Then they take our souls out of our bodies at night via the feet & take them up through the branches of the tree of god to the other levels of the heavens; which are simply platforms on God's tree.
Last night an Angel of God showed me the tree Of God reaching into the infinity of space below me with many platforms branching out from its trunk & a channel running through the centre. And The Tree of God reached out & touched me with an oak leafed branch in an affectionate way.
I've seen the tree of God many times & God Himself took me to Eden to see it as well.
So your Angel or God was just showing you God's Tree & the spiritual beings that come from it, & trying to explain that the spiritual beings come in vessels & connect to this world through holes in people's feet, & it's like entering a pyramid with spiritual power inside that lets them witness the blue sky of this world with us.
When people die they find themselves in a tunnel heading to the light. That tunnel is the inside of the branch of God's Tree that holds onto their bodies. Their soul is brought into the body through it & taken out the same way. The sap of god's tree is a liquid light & that's why we head back to the light when we die
