The Madhyamaka logic is like this:
Because everything is 𝗱𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝘁𝗹𝘆 𝗰𝗼-𝗮𝗿𝗶𝘀𝗲𝗻 (co-dependent with something else, ex, with its parts, with its causes & conditions, with its conceptual opposite(s), and 𝗰𝗼-𝗱𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝘁 𝘄𝗶𝘁𝗵 𝘁𝗵𝗲 subject / 𝗺𝗶𝗻𝗱 𝗺𝗲𝗿𝗲𝗹𝘆 𝗹𝗮𝗯𝗲𝗹𝗹𝗶𝗻𝗴 / 𝗶𝗺𝗽𝘂𝘁𝗶𝗻𝗴 / 𝗰𝗼𝗻𝗰𝗲𝗽𝘁𝘂𝗮𝗹𝗶𝘀𝗶𝗻𝗴 𝗶𝘁 in dependence of its past / conditioning / karma)
<==> then everything is 𝗲𝗺𝗽𝘁𝘆 𝗼𝗳 𝗶𝗻𝗵𝗲𝗿𝗲𝗻𝘁 𝗲𝘅𝗶𝘀𝘁𝗲𝗻𝗰𝗲;
<==> then there is 𝗻𝗼 𝗿𝗲𝗮𝗹 𝘁𝗵𝗿𝗲𝗲 𝘀𝘁𝗮𝗴𝗲𝘀 𝗼𝗳 𝗯𝗲𝗰𝗼𝗺𝗶𝗻𝗴 -- origination / beginning / birth / coming, duration / middle / life, cessation / ending / death / going -- for anything;
<==> then there is 𝗻𝗼 𝗿𝗲𝗮𝗹 𝗽𝗲𝗿𝗺𝗮𝗻𝗲𝗻𝗰𝗲 / 𝗰𝗼𝗻𝘁𝗶𝗻𝘂𝗶𝘁𝘆 / 𝗲𝘁𝗲𝗿𝗻𝗶𝘁𝘆, 𝗻𝗼 𝗿𝗲𝗮𝗹 𝗶𝗺𝗽𝗲𝗿𝗺𝗮𝗻𝗲𝗻𝗰𝗲 / 𝗱𝗶𝘀𝗰𝗼𝗻𝘁𝗶𝗻𝘂𝗶𝘁𝘆 / 𝗮𝗻𝗻𝗶𝗵𝗶𝗹𝗮𝘁𝗶𝗼𝗻 either for anything; nothing exist and change (movement), or remain the same (stillness);
<==> then 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 𝗶𝘀 𝗻𝗼𝘁 𝗲𝘅𝗶𝘀𝘁𝗲𝗻𝘁, 𝗻𝗼𝗻-𝗲𝘅𝗶𝘀𝘁𝗲𝗻𝘁, 𝗻𝗼𝘁 𝗯𝗼𝘁𝗵 𝘁𝗼𝗴𝗲𝘁𝗵𝗲𝗿, 𝗻𝗼𝘁 𝗻𝗲𝗶𝘁𝗵𝗲𝗿;
𝗻𝗼𝘁 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 / 𝘀𝗲𝗽𝗮𝗿𝗮𝘁𝗲 / 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗲 / 𝗱𝘂𝗮𝗹, 𝗻𝗼𝘁 𝗶𝗱𝗲𝗻𝘁𝗶𝗰𝗮𝗹 / 𝘂𝗻𝗶𝘁𝗲𝗱 / 𝗼𝗻𝗲 / 𝗻𝗼𝗻-𝗱𝘂𝗮𝗹, 𝗻𝗼𝘁 𝗯𝗼𝘁𝗵 𝘁𝗼𝗴𝗲𝘁𝗵𝗲𝗿, 𝗻𝗼𝘁 𝗻𝗲𝗶𝘁𝗵𝗲𝗿;
not permanent / continuous / eternal, not impermanent / discontinuous / annihilated, not both together, not neither;
not unequal / impure / imperfect / ordinary, not equal / pure / perfect / divine, not both together, not neither;
not this, non-this, not both together, not neither;
meaning 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 𝗶𝘀 𝗶𝗻𝗰𝗼𝗻𝗰𝗲𝗶𝘃𝗮𝗯𝗹𝗲 , 𝗯𝗲𝘆𝗼𝗻𝗱 𝗮𝗹𝗹 𝗰𝗼𝗻𝗰𝗲𝗽𝘁𝘂𝗮𝗹 𝗽𝗿𝗼𝗹𝗶𝗳𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀, 𝗯𝗲𝘆𝗼𝗻𝗱 𝗮𝗹𝗹 𝗲𝘅𝘁𝗿𝗲𝗺𝗲𝘀 & 𝗺𝗶𝗱𝗱𝗹𝗲;
<==> then there is 𝗻𝗼 𝗿𝗲𝗮𝗹 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲 / 𝘀𝗲𝗽𝗮𝗿𝗮𝘁𝗶𝗼𝗻 / 𝗼𝗽𝗽𝗼𝘀𝗶𝘁𝗶𝗼𝗻 / 𝗿𝗲𝗹𝗮𝘁𝗶𝗼𝗻 / 𝗱𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝗰𝗲 / 𝗱𝘂𝗮𝗹𝗶𝘁𝘆, 𝗻𝗼 𝗿𝗲𝗮𝗹 𝗶𝗱𝗲𝗻𝘁𝗶𝘁𝘆 / 𝘀𝗮𝗺𝗲𝗻𝗲𝘀𝘀 / 𝘂𝗻𝗶𝘁𝘆 / 𝗲𝗾𝘂𝗮𝗹𝗶𝘁𝘆 / 𝗻𝗼𝗻-𝗱𝘂𝗮𝗹𝗶𝘁𝘆 / 𝗼𝗻𝗲𝗻𝗲𝘀𝘀 / 𝗶𝗻𝗱𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝗰𝗲 either;
<==> then 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 𝗶𝘀 𝗯𝗲𝘆𝗼𝗻𝗱 𝗮𝗹𝗹 𝗼𝗽𝗽𝗼𝘀𝗶𝘁𝗶𝗼𝗻 / 𝗱𝗶𝘀𝗰𝗿𝗶𝗺𝗶𝗻𝗮𝘁𝗶𝗼𝗻 / 𝗱𝘂𝗮𝗹𝗶𝘁𝗶𝗲𝘀;
<==> so 𝘁𝗵𝗲𝗿𝗲 𝗶𝘀 𝗻𝗼𝘁𝗵𝗶𝗻𝗴 𝘁𝗼 𝗮𝗰𝗰𝗲𝗽𝘁 / 𝗮𝗳𝗳𝗶𝗿𝗺 / 𝘀𝗲𝗲𝗸 / 𝗱𝗼 / 𝗮𝗱𝗱 in absolute terms, 𝗻𝗼𝘁𝗵𝗶𝗻𝗴 𝘁𝗼 𝗿𝗲𝗷𝗲𝗰𝘁 / 𝗻𝗲𝗴𝗮𝘁𝗲 / 𝗮𝗯𝗮𝗻𝗱𝗼𝗻 / 𝗻𝗼t-𝗱𝗼 / 𝘀𝘂𝗯𝘁𝗿𝗮𝗰𝘁 in absolute terms, just conventionally / relatively / intersubjectively;
<==> so, we say that 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 𝗶𝘀 𝗮𝗹𝗿𝗲𝗮𝗱𝘆 𝗲𝗾𝘂𝗮𝗹, 𝗽𝘂𝗿𝗲, 𝗽𝗲𝗿𝗳𝗲𝗰𝘁, 𝗱𝗶𝘃𝗶𝗻𝗲, 𝗵𝗲𝗿𝗲 & 𝗻𝗼𝘄.
Ex. Purity is in the eye of the beholder. What purifies / transmutes samsara into nirvana is the direct wisdom of being fully aware of the true nature & dynamic of everything, of Reality / Mind. Fabrications (physical, conceptual, mental) in themselves are not bad / impure, not good / pure, not both together, not neither.
So, Just relax! Let it be! Enjoy the magical show of Reality / Mind!
Note: <==> means one implies the other.
The unity of emptiness ~ Sengcan
Things are OBJECTS because there is a SUBJECT or mind;
and the mind is a SUBJECT because there are OBJECTS.
Understand the relativity (co-dependence) of these two
and the basic reality: the unity of emptiness.
In this Emptiness the two are indistinguishable
and each contains in itself the whole world.
If you do not discriminate between coarse (impure mind) and fine (pure mind)
you will not be tempted to prejudice and opinion.
translated by Richard B. Clarke
(i.e. This expresses very well the true nature of Reality as it is here & now: the inconceivable Union of the Two Truths about the three spheres: That the three spheres -- subject / mind, relation / action, objects / phenomena -- are empty of inherent existence (2nd truth) <==> exactly because co-dependent (1st truth). So, meditation should not be about trying to reduce everything to the mind (mind-only view), no more than to phenomena-only, or processes/relations-only ...
A lot of buddhists miss this point and fall into idealism and have a tendency to reject what is not 'pure mind'.
This is also why a strong basis in Madhyamaka is a prerequisite to any meditation.)
Doer and doing ~ Nagarjuna
A doer (subject) arises dependent on a doing (action),
and a doing (action) exists dependent on a doer (subject).
(i.e. The same thing with the object)
Except for that, we do not see another cause for their establishment.
quoted in the book Meditation on Emptiness
The Innate Beyond Subject And Object ~ Dilgo Khyentse Rinpoche
Phenomena (objects) are the radiance of the innate absolute;
Mind’s nature (subject) is the wisdom of the innate absolute.
(i.e. The same with their relation / action)
The ultimate teacher – phenomena (objects) and mind (subject) merged in one taste (Union) –
Dwells naturally within myself.
(i.e. Directly abiding on the self-arisen unalterable pristine Ground / true nature & dynamic of Reality: the Union of the Two Truths about the three spheres -- subject / mind, relation / action, objects / phenomena.)
Ah ho! What a joy!
-- Dilgo Khyentse Rinpoche
quoted in the book The Tibetan Buddhism Reader
A mere indescribable luminosity ~ Maitreya
If what appears to be apprehended (object / phenomena) does not exist by its very own essence apart from that (subject) which apprehends (action) it, then what appears to be the apprehender (subject / mind) does not exist either.
(i.e. Union of the Two Truths about the three spheres: The three spheres -- subject / mind, relation / action, object / phenomena -- are empty of inherent existence (2nd truth) <==> because co-dependent, co-emergent, co-evolving ...(1st truth).)
The reason, here, is that the apprehender (subject) exists in relation to the apprehended (object), not in isolation.
Therefore, awareness (Ground / Reality / Suchness) is devoid of both apprehender (subject) and apprehended (object) (and relation / action), in all their various forms.
Free from subject and object (and action), by its very own nature awareness is a mere indescribable luminosity (Union of the Two Truths: empty luminosity).

MADHYAMAKA LOGIC point of view:
Because everything is 𝗖𝗢-𝗗𝗘𝗣𝗘𝗡𝗗𝗘𝗡𝗧 / dependently co-arisen, ever changing, merely labelled / imputed / conceptualised / opposed by the mind in dependence of its past / conditioning / karma;
<==> then everything is 𝗘𝗠𝗣𝗧𝗬 of inherent existence <==> then there is NO REAL ORIGINATION, DURATION, CESSATION of anything;
<==> then there is no real permanence / continuity / eternity, no real impermanence / discontinuity / annihilation of anything;
<==> then everything is NOT EXISTENT, NOT NON-EXISTENT, not both together, not neither;
NOT DIFFERENT / SEPARATE / MULTIPLE / DUAL, NOT IDENTICAL / UNITED / ONE / NON-DUAL, not both together, not neither;
NOT PERMANENT / CONTINUOUS / ETERNAL, NOT IMPERMANENT / DISCONTINUOUS / ANNIHILATED, not both together, not neither;
NOT UNEQUAL / IMPURE / IMPERFECT / ORDINARY, NOT EQUAL / PURE / PERFECT / DIVINE, not both together, not neither;
NOT RELATIVE, NOT ABSOLUTE, not both together, not neither;
𝗡𝗢𝗧 𝗧𝗥𝗨𝗘 / 𝗥𝗜𝗚𝗛𝗧, 𝗡𝗢𝗧 𝗙𝗔𝗟𝗦𝗘 / 𝗪𝗥𝗢𝗡𝗚, 𝗻𝗼𝘁 𝗯𝗼𝘁𝗵 𝘁𝗼𝗴𝗲𝘁𝗵𝗲𝗿, 𝗻𝗼𝘁 𝗻𝗲𝗶𝘁𝗵𝗲𝗿;
NOT RELATIVE, NOT ABSOLUTE, not both together, not neither;
NOT PURELY-OBJECTIVE, NOT PURELY-SUBJECTIVE, NOT PURELY-PROCESS, not two or three of them together, not none of them;
NOT PURELY-PHYSICAL, NOT PURELY-CONCEPTUAL, NOT PURELY-MENTAL, not two or three of them together, not none of them;
NOT THIS, NON-THIS, not both together, not neither;
-- meaning the true nature of Reality is beyond all extremes & middle, beyond all conceptual proliferations, beyond all conditioning / karma, inconceivable for our flawed conditioned conceptual dualistic minds --;
<==> then there is no real difference / separation / opposition / relation / dependence, no real identity / sameness / unity / equality / oneness / independence;
<==> then everything is beyond all opposition / discrimination / dualities in absolute terms;
<==> then there is 𝗡𝗢𝗧𝗛𝗜𝗡𝗚 𝗧𝗢 𝗔𝗖𝗖𝗘𝗣𝗧 / affirm / seek / do / add in absolute terms,
𝗡𝗢𝗧𝗛𝗜𝗡𝗚 𝗧𝗢 𝗥𝗘𝗝𝗘𝗖𝗧 / negate / abandon / non-do / subtract in absolute terms,
just conventionally / relatively / intersubjectively;
<==> the we might as well say that
𝗘𝗩𝗘𝗥𝗬𝗧𝗛𝗜𝗡𝗚 𝗜𝗦 𝗣𝗥𝗜𝗠𝗢𝗥𝗗𝗜𝗔𝗟𝗟𝗬 𝗘𝗤𝗨𝗔𝗟 / 𝗣𝗨𝗥𝗘 / 𝗣𝗘𝗥𝗙𝗘𝗖𝗧 / 𝗗𝗜𝗩𝗜𝗡𝗘 / TIMELESS / SPACELESS / LIMITLESS / INCONCEIVABLE … as an antidote to our usual position; and enjoy the magical show, appreciating both the diversity and unity of everything, never grasping at any position, never becoming slaves to conditioned views, methods & goals, never accepting this & rejecting that in absolute terms. Realising the true nature & dynamic of anything & everything is the liberating factor, the door to timeless bliss.)
