External phenomena appear within space, remain within space and disappear within space again. Is there any place where earth, water, fire and wind can go that is outside space? Don’t they always remain within space? When they disintegrate, isn’t it within space that they dissolve? Is there any place at all to go to which is beyond or outside space, which is somewhere other than space? Please understand very well this symbolic resemblance between dharmadhatu and physical space.
