The root of all our problems

The whole material world is working on the basis of “I” and “mine.” This is
the root of attraction to the material world. If one is attracted to this
root of illusory conceptions — “I” and “mine” – he will have to remain
within this material world.
(SB 4.11.30p)
The karmi thinks of this world as “mine,” and the jnani thinks “I am”
everything.”
(SB 2.9.2p)
