Hi Lal,
“In addition, we receive sense inputs exclusively through the mind-door. They come through the mana indriya in the brain (not known to modern science).”
The dhamma that we perceived in our mind are actually kamma beeja stored in the Mano Loka that has ripen, having its energy unleashed in the form of random thoughts (vipaka) that impinged on our mana indriya, right?
