In total, Totality in Buddhism is the functioning of all 18 Dhatus. As Thusness comments further, an insight practitioner further does away with mental labeling and perceptions, and experiences 18 Dhatus as 18 Dhatus (as Thusness and my Dharma teacher used to say, a practitioner only has the first 2 skhandas in play, while perception, volition, and dualistic consciousness is dissolved through practise, insight and bare awareness), only sense awareness and objects of sense awareness.

"The Tathagata — a worthy one, rightly self-awakened — directly knows earth as earth. Directly knowing earth as earth, he does not conceive things about earth, does not conceive things in earth, does not conceive things coming out of earth, does not conceive earth as 'mine,' does not delight in earth. Why is that? Because the Tathagata has comprehended it to the end, I tell you.
"He directly knows water as water... fire as fire... wind as wind... beings as beings... gods as gods... Pajapati as Pajapati... Brahma as Brahma... the luminous gods as luminous gods... the gods of refulgent glory as gods of refulgent glory... the gods of abundant fruit as the gods of abundant fruit... the Great Being as the Great Being... the dimension of the infinitude of space as the dimension of the infinitude of space... the dimension of the infinitude of consciousness as the dimension of the infinitude of consciousness... the dimension of nothingness as the dimension of nothingness... the dimension of neither-perception-nor-non-perception as the dimension of neither-perception-nor-non-perception... the seen as the seen... the heard as the heard... the sensed as the sensed... the cognized as the cognized... singleness as singleness... multiplicity as multiplicity... the All as the All...
"He directly knows Unbinding as Unbinding. Directly knowing Unbinding as Unbinding, he does not conceive things about Unbinding, does not conceive things in Unbinding, does not conceive things coming out of Unbinding, does not conceive Unbinding as 'mine,' does not delight in Unbinding. Why is that? Because the Tathagata has comprehended it to the end, I tell you.

Directly knowing earth as earth, he does not conceive things about earth, does not conceive things in earth, does not conceive things coming out of earth, does not conceive earth as 'mine,' does not delight in earth. Why is that? Because he has known that delight is the root of suffering & stress, that from coming-into-being there is birth, and that for what has come into being there is aging & death. Therefore, with the total ending, fading away, cessation, letting go, relinquishment of craving, the Tathagata has totally awakened to the unexcelled right self-awakening, I tell you.

That is what the Blessed One said. Displeased, the monks did not delight in the Blessed One's words.
