Is Nibbana/Nirvana non-substantial? I ask because of the below quote.
"His release, being founded on truth, does not fluctuate, for whatever is deceptive is false; Unbinding — the undeceptive — is true. Thus a monk so endowed is endowed with the highest determination for truth, for this — Unbinding, the undeceptive — is the highest noble truth."
Everything that makes you, you, is the result of your Environment (Society, Culture, Family, Friends, Etc), Genetics/Biology (Your brain which makes the mind possible, Inborn diseases such as Down Syndrome, or even Psociopathy, etc), Thoughts (Everything you think affects your mind, and the person you are), Speech (Same as thoughts, but words affect your environment as well), Actions (Same as Speech), and the Elements (Earth, Water, Fire, Wind, Space, and Time).
