Acharn: At the moment of seeing, are there inner and outer rupas? Can visible object be an inner rupa?
Lukas: Of course. The outer is only others. All 5 khandhas that are other beings is always bahjda and refers to others. Not only rupa, but all 5 khandha can be ajjhata/bahidda satipathana sutta. internal or external, check vibhanga pali, khandha vagga czapter one, instances of 5 khandhas. It's all to be understood.
