Years ago on an old blog, I received a comment that was the harshest rebuke I’ve ever received. The blog itself has questionable content, but looking back, this rebuke is still awesome.
What life-long profound and comprehensive discipline have you engaged in to enable you to presume to lecture others on how they should live?
Who were/are your LIVING Spiritual Teachers? Such Teachers being necessary to guide you and more importantly to challenge you to examine ALL of your ideas and opinions about quite literally everything.
Have you been humbled by your own sweat and suffering?
If you read the biographies of the great Saints and Realizers from all of the traditions you will find that most of them went through a profound ordeal of struggle and testing until they came to their Spiritual maturity—it often took decades.
You are mortal and entirely subject to the Mercy of The Divine. You own nothing and know nothing. There is not anything to be believed that is the Truth.
You must be touched in your feeling by the unspeakable suffering of this world, and thus become broken hearted. It is only on that basis that you can truly serve others.
Everything else is just an extension of your own unexamined obnoxiousness, and your drive to achieve power and control over others.
