My original point, exactly. Mind is but an imaginary container for the six consciousnesses. However a mind devoid of The Khandas, all manner of defilements, hindrances, fetters, free from all manner of fermentations could easily be described as brilliant, lusterous, sqeaky clean, and luminous. Each practitioner who has experienced such a mind, would reasonably be expected to describe it as such. Ven. Bua's description of "almost" purified citta seems similar, and having apparently experienced periodic episodes of purified citta, he explains that it is beyond description, so there is no point in even attempting such an explanation to others, who have not experienced it for themselves.tiltbillings wrote: This just sounds like reifying citta. Let us not forget that the sutta immediately preceding the "luminous" mind sutta states: "I don't envision a single thing that is as quick to reverse itself as the mind — so much so that there is no feasible simile for how quick to reverse itself it is."
I conclude, however, as stated previously, that purified citta is not nibbana, therefore impermanent. However, I will reserve judgement until actually having experienced it, just as no one can know what it is like to cross The Event Horizon of a Black Hole until one's subatomic particles are ripped, and his resultant energy spread across the universe. "You just had/have to be there to understand."
Having never experienced purified citta for myself, not even certain if I have actually experienced Jhanna-I, or Jhanna-II, this means to me that the only thing left (for me) to do is study, practice, and look for the beacon. (Sounds familiar for some reason.)
