The Chain of Craving for Formless Existence is attraction to the Equanimity of 4 formless absorptions...

The Mental Chain of the Conceit: “I AM” is the narcissism, that there IS an 'Ego', that remains as the same...

The Chain of Restlessness is the obsessed addiction to all making, intending, planning, doing, constructing...
The Chain of Ignorance is the not seeing, not understanding and not knowing directly the 4 Noble Truths...
