When we categorize our sufferings - as physical and mental, its vivid that 95% of our sufferings are mental.
Mental sufferings (suffer of anger, suffer of hatred, suffer of jealousy, suffer of fear, suffer of greed, suffer of insecurity ) roots from - Expecting absolute values from the world which is constantly relative.
Mind is a collection of illogical, unconnected,unclutched independent thoughts, its ever changing nature brings high volatility to the worldly things on which we expect or seek absolute meaning.
This is like identifying/distinguishing a pot of water from river. When river is continuously running, water becomes dynamic phenomenon and water at a moment cannot be identified in the next moment.NEVER ever imagine this will happen ever.
When we realize that you can never expect ABSOLUTE or PERFECTION from any worldly things, you would see, suffering is not caused by anyone and/or anything outside but solely originates within yourself.
As soon as one smells a pit any kind of mental suffering in oneself,wake up, retrospect, LET IT PASS [ACCEPT IT FULLY - THERE IS NO ABSOLUTE VALUE] whatever be the reason mind may try to advocate.The sooner one identifies the suffering, the quicker the relief. With suffering we will worsen the situation and we cannot achieve any better state.
The compassionate practice of this technique removes all traces of our sufferings.
Then we can see - suffering is after all a choice - YOUR choice.Not imposed by anyone or anything outside.
OH.Thee! Let these truths be imbibed into every cell of our body so we remember them even unconsciously.
