...So on and So forth...

Everything that happens, is for a purpose. Good or bad - is a different story.

Knowledge is without bounds... what you choose to remember and carry forward in life [and beyond] is limited.
The Self is the only gateway to realization. The only bond with the world and the Godhead; hence the most basic and important part of existence. Integrity is how you choose to stand by the Self- the discipline you inherently apply to your beliefs and actions.
The Self is the way it is now be-cause of so many incidents and experiences of the past [which occurred on purpose].
When the Self becomes predominant and not it's essence - you create an arrogant monster covered with scabs and wounds that can never heal.
When the Self is forgotten and its essence belittled or shrunk - you lose the crux of existence, the connection to the Godhead - therefore, the purpose of your life, whether it's salvation, redemption or achievement.
The Self is to be experienced, understood and improved. It has to be made useful and its learnings shared relevantly. Its desires achieved to establish what's called the Cycle of Life and Death.
