Difficult to understand – the words of a great Saint
I have the translation here
Struck by a bladless spear, he sits under the tree
Surely he will die either today or tomorrow.
This is a difficult passage to understand, but this is my interpretation. Bladeless spear – is awakening of the shakti. It is a spear since it penetrates the chakras. The tree is the passage to Sahastrar and sitting refers to meditation. Surely he will die today or tomorrow – meaning Moksha is certain in a few births.
The tree is Brahmanadi or sushumna
Death is Death of ego
