Earth cannot really be owned. Property title may create a very convincing illusion of ownership, but that illusion can only continue for as long as there is division in the mind.
Moreover, the only kind of security that comes from personal ownership of property is a false sense of security in worldly things.
In reality, all struggle comes from thinking that separation is real, and no matter how much is done to get security and avoid struggle, life will continue to being whatever is necessary to reveal that separation is an illusion.
The more there is willingness to have everything come and go exactly as it does, the more ease and grace is allowed to be experienced and shared with all beings.
Love and abundant blessings!
