When you enter a new situation, a new job, a new city, a new life, what are your primary concerns?
We are concerned about our parents and teachers, the neighborhood and school district, the crime and homelessness. We care about the class we are in or the team we are on. Reputation, notoriety and association are all a big deal.
These are deep seated concerns. We care about where we are born. We have an innate predisposition to seek out positive rebirths, positive circumstances.
The purification of rebirth isn't to be reborn in the wealthiest neighborhood with the best schools and the best odds of getting into the best colleges with the best sports teams. No. The purification of birth is to able to enter any situation, any circumstance, any life and to be unstained by its faults.
When we are able to take any form and not be bound, then we are truly free. Taking the conditions that you find yourself in, using them as the basis of the path, and transforming them through wisdom to bring benefit to others, that is freedom.
The rest is just bondage in gold chains.
