Of course, gandhabba has the five aggregates.
As I wrote above, we are all gandhabbas inside “physical shells”.
– The physical body is inert (lifeless) when the gandhabba comes out.
– Try to think logically. How do people who have “out-of-body experiences” see and hear OUTSIDE the physical body. At that time they have only the “gandhabba kaya” or the “manomaya kaya”.
