3 marks of existence: conditioned vs unconditioned things? The Wikipedia page for &quot;the 3 marks of existence&quot; differentiates between &quot;conditioned things&quot; and &quot;unconditioned things&quot; like so:

The three marks are:

sabbe saṅkhārā aniccā — &quot;all saṅkhāras
(conditioned things) are impermanent&quot;
sabbe saṅkhārā dukkhā — &quot;all
saṅkhāras are unsatisfactory&quot;
sabbe dhammā anattā — &quot;all dharmas
(conditioned or unconditioned things) are not self&quot;


The Buddha said &quot;I teach one thing and one thing only. Suffering and the end of suffering.&quot;
Within that context:

What is the difference between a &quot;conditioned thing&quot; and an &quot;unconditioned thing&quot;?
How does that difference give meaning to the 3 marks?
How does this meaning point towards &quot;the end of suffering&quot;?
All compounded and/ or conditioned things are impermanent or changing. This applies to the five aggregates, physical objects, matter, energy, physical space, time, most mental concepts and ideas etc.
All matter can be broken down to energy. Energy can be converted to matter. That we know from Einstein's E=mc2. Matter can convert into different forms and so can energy.
Physical space and time can be warped by matter. This we know from Einstein's Theory of General Relativity.
Conditioned things are impermanent and a source of suffering.
Nibbana is not impermanent. It is not conditioned or compounded. It does not depend on anything else. From this answer, we read:

So, Nibbana is not a thought of the mind, not a concept of the mind,
not a state of the mind, not a state of consciousness and also not a
feeling. However, when the mind experiences this Nibbana, which is not
conditioned, not compounded, not suffering, not impermanent, not
arising, not ceasing and not changing, it experiences bliss. The mind
can therefore experience Nibbana, but it cannot feel it or think about
it.

However, all things including Nibbana, Buddha's teachings, matter, physical space, time, thoughts, concepts are not self. There is no permanent, standalone, independent thing called self, just as you cannot find a thing called music when you breakdown a musical instrument into its constituent parts.
