When Guru Rinpoche thaught Yeshe Tsogyal about all dharmas and dharmata, he said that all dharmas are whether wholesome, unwholesome or neutral phenomena.
Dharmata means that all are empty in essence, empty by nature, empty by characteristics. Dharmata is the realization that ALL phenomena arise from the mind which is emptiness.
This is the point of realizing the nonduality of dharmas and dharmata.
One of his explanation in dissolving limitations.
Phenomena liberated in themselves.
Excuse me Muni, your posts (1000+ in number) always seem to me you speculating vaguely only without getting the real instructions. First I met you in forums on madhyamaka, where you also speculated as i understood you. Of course it is only subjective opinion of mine. Considering it, you better find a master of Dzogchen, get DI and start the preliminary practice (for example the Rushen) as soon as possible, than you will recognize as really those instructions teach. Good luck
