No, a simple jab of knife does not have the ability to kill the tree. It has to go through various processes. If its root is not removed from the earth, it will sprout again.
The tree consumes the earth, and rises out it feeding upon its crust. It absorbs years of sunlight, air and water.
‘Bleeding bark’ means the twigs which are cut mercilessly. They leave a liquid substance. If any part of the human body is cut, it starts bleeding. In the same way the liquid substance comes out from the branch of a tree. The human beings’ axe makes it bleed.
‘No’ is used to emphasize the perspective that chopping or hacking will not be sufficient for killing a tree.
It means that the earth protects it like a mother. ‘Earth Cave’ implies a hole inside it. The tree allows its roots to spread underneath. The earth protects it and fosters it. It provides all the essential ingredients to the tree.
The stem/root is the strength of a tree. When the tree is pulled out, its strength is exposed.
Pulling out the tree from the mother earth and scorching and choking it in the sun and air kill the tree. It becomes brown, dry and gets hard. Eventually it dies.
