To say that "all consciousness is not permanent" may be going too far.
SN 35:23 indicates that the “all” in “all that is sensed, being
unrelished, will grow cold right here” denotes the six sense media.
The term “Such” refers to the fact that the arahant’s attainment is
effortlessly unaffected by the arising or passing away of anything
related to the six senses. Because sensory consciousness arises in
dependence on the six sense media, this Suchness is unaffected at the
arahant’s death, when sensory consciousness totally ends.
However, a third analogy raises the question of whether there is another mode of
consciousness unaffected by the arahant’s death. In this analogy,
awakened consciousness is depicted not as a seed but as a beam of
light, the four nutriments of consciousness are the various places
where a beam of light might land, while passion and delight are the
means of its landing.
“Where there is no passion for the nutriment of
physical food, where there is no delight, no craving, then
consciousness does not land there or 118 grow. Where consciousness
does not land or grow, name-&-form does not alight. Where name-&-form
does not alight, there is no growth of fabrications. Where there is no
growth of fabrications, there is no production of renewed becoming in
the future. Where there is no production of renewed becoming in the
future, there is no future birth, aging, & death. That, I tell you,
has no sorrow, affliction, or despair.
[Similarly with the nutriment
of contact, intellectual intention, and consciousness.]
“Just as if
there were a roofed house or a roofed hall having windows on the
north, the south, or the east. When the sun rises, and a ray has
entered by way of the window, where does it land?” “On the western
wall, lord.” “And if there is no western wall, where does it land?”
“On the ground, lord.” “And if there is no ground, where does it
land?” “On the water, lord.” “And if there is no water, where does it
land?” “It does not land, lord.”
“In the same way, where there is no
passion for the nutriment of physical food … contact … intellectual
intention … consciousness, where there is no delight, no craving, then
consciousness does not land there or grow. Where consciousness does
not land or grow, name-&-form does not alight. Where name-&-form does
not alight, there is no growth of fabrications. Where there is no
growth of fabrications, there is no production of renewed becoming in
the future. Where there is no production of renewed becoming in the
future, there is no future birth, aging, & death. That, I tell you,
has no sorrow, affliction, or despair.” — SN 12:64
This analogy does
not specifically state whether it refers to the arahant before or
after death. However, in the context of this analogy, the beam of
light depends on the wall, the ground, etc., only for the fact of its
appearance and growth within space and time. This suggests that it
otherwise would not be affected when the nutriments disappear. Thus
the analogy would refer to the arahant both before and after death.
This interpretation is supported by two contexts, one authorial and
the other textual. The authorial context is that if the Buddha’s
Awakening had revealed that total Unbinding was a state of total
unconsciousness, he would never have thought of using this analogy to
describe the awakened state.
The textual context is provided by MN 49,
which states that—in contrast to the consciousness of an unawakened
being, which is known only through its interaction with kamma—the
arahant’s knowledge of unconditioned consciousness is totally
unmediated.
“‘Having directly known the all [the six sense media and
their objects—see SN 35:23] as the all, and having directly known the
extent of what has not been experienced through the allness of the
all, I wasn’t the all, I wasn’t in the all, I wasn’t coming forth from
the all, I wasn’t “The all is mine.” I didn’t affirm the all ….
“‘Consciousness without surface, without end, luminous all around,
has not been experienced through the earthness of earth … the liquidity of
liquid … the fieriness of fire … the windiness of wind … the
being-ness of beings … the deva-ness of devas … the Pajapati-ness of
Pajapati … the brahma-ness of Brahma … the radiant-ness of the radiant
(devas) … the beautiful black-ness of the beautiful black (devas) …
the sky-fruit-ness of the sky-fruit (devas) … the conqueror-ness of
the conqueror … the allness of the all.’” — MN 49
