(citta=mind or consciousness)
Nowadays, many meditators_yogi contemplate that mind, body, life or everything-etc; is impermanent, unsatisfactory and non-self.
It is because of mistaking that life(mind & body) our habitual perceptions can detect is real and existing for a certain period. In other words, we are misunderstanding that mind & body we contemplate are the Citta, Ceticeka, and Rupa the Buddha taught as original truths.
In Abhidhamma(Original truth_higher teaching of the Buddha), it says that there is only one mind or consciousness(citta) at a time for a mental process.
In reality(in original truth), one mind or consciousness can arise after the previous one has already disappeared. This is the natural law of mental process.
In other words, each consciousness has to cease before the next one arises. One consciousness can appear after the previous one has already gone.
In reality, observing mind or mindful consciousness or mindfulness can’t see the real arising and passing away of the previous mind such as feeling, perception, volition or thinking etc; which is assigned as the object of meditation in cittanupassana and vedananupassana (contemplation of mind and feeling).
Because observing mind or mindfulness can arise after the previous mind or feeling or volition or thinking-etc has already disappeared according to the psychic order or natural law of mental process.
That means the mind such as thinking or feeling or perception or volition or desire etc; our mindfulness is contemplating is not real. Thus, our contemplation of Anicca, dukkha, anatta concerning with the mind and body we are now understanding is also untrue and fake and fraud.
It is because of the deceitful actions or creations of the momentum of the previous minds which have already vanished.
In fact, one mind feels, perceives, knows or acts upon only the situation of nothing after the previous mind has already passed away.
But it means to accept, contemplate and understand that whatever our mind can now perceive is just created truth or fraud by (sankhara dukkha)real impermanence(constant vanishing nature in very high rate) by understanding and remembering that natural law of "one citta at a time" that one mind cannot see the previous mind arising and existing.
By accepting and contemplating like that, we become able to abandon the attachment, grasping and centering upon whatever our mind can now perceive as reality and as of real importance.
