Existence, non-existence, change - this is the nature of things. Realizing this, stillness, serenity and bliss naturally follow. One who knows for certain that “Self creates All and is alone” becomes still, desireless, unattached. One who knows for certain that adversity and success come and go in obedience to destiny becomes content. He neither desires nor grieves. One who knows for certain that birth and death, happiness and misery, come and go in obedience to destiny sees nothing to accomplish. He engages in non-action, and in action remains unattached.
