By the way, when I said "occasional itching for physical/sense pleasures could arise for those who experienced higher mental pleasures through Samadhi", what I meant is 'those' who have cut down ONLY a several layers of curtains (of communal gravity cosmic jail) since even with few layers being cut down, one can get a taste of such a blissful state. But those few who cut down the ENTIRE layers for good, there is no itching. Any of clinging/grasping for pleasure or becoming/formation process is gone for those noble ones. BTW, I still have that occasional itching and my virtues are still lacking (except 'discipline') so I am just a traveler. I am just sharing a travelling tip in the desert battle zone. But the key to unlock the door from the regular middle zone/ in-between zone (that is between Samadhi and normal consciousness) to the desert battle zone is 'five sense based pleasure restraint' and it has to be continuous/ without any break. (Also, I might share some techniques to strengthen the survival mechanism in the desert in the future.)
