How can all dharmas have no intrinsic reality logically speaking? There Can Only Be Two Types of Realities(Dharmas):
1.Conditioned Reality: Any reality that depends on something for its existence. For example, a Cow depends on its organs, the organs depend on cells, the cells depend on molecules, which depend on atoms,wich depend on electrons,wich depend on Quarks and so forth. This dependence is simultaneous at every moment the conditioned reality exists.
2.Unconditioned Reality: Any reality that is self-sufficient, i.e. does not depend on anything else for its existence. This is what is called “Brahman''(The one Spirit ''or ''Ishwara''(God).
any conditioned reality depends upon another reality in order to exist by definition.
Any conditioned Dharma, must depend upon:
a finite number of conditioned Dharmas alone
or an infinite number of conditioned Dharmas alone
or a finite number of conditioned Dharmas and at least one unconditioned Dharma
A conditioned Dharma cannot be caused by a finite series of conditioned Dharma: If there is a linear series of conditioned Dharma, what would the first one depend on? Since it must depend on something, and there is nothing before it, the whole chain ceases to exist. Thus a linear chain of conditioned realities cannot exist. Additionally, a circular finite chain of conditioned Dharmas could not exist either. This would simply result in each conditioned reality fulfilling their own conditions, which is against the definition of a conditioned Dharma.
Conditioned realities cannot exist in an infinite Series either. A very large unlimited of number conditioned realities cannot exist,. As the number of conditioned realities in a series increases, the result continues to be non-existence. Continuously adding to the end of the chain would never allow for the conditions of existence to be satisfied, thus the entire infinite chain of conditioned Dharmas would never have its conditions fulfilled.
If an infinite (I am granting You guys the notion that a actual Infinite can exist in quantity for the sake of argument,I do not Believe this)series of conditioned Dharmas could exist on its own, the complete set of infinite conditioned Dharma would be an unconditioned Dharma. However, this is impossible because an unconditioned dharma cannot depend upon an aggregate of conditioned dharmas . if this were the case, it would be conditioned. Therefore, a set of infinite conditioned realities is itself a conditioned reality, and fails to exist on its own.
Since any model made up entirely of conditioned Dharmas can never have their conditions fulfilled, every conditioned Dharma must be caused by a series of realities that ends (or begins its ontological Series) with an unconditioned Dharma.
Thus it Seems that a intrinsic Existance does exist?So how can Shunyata and sarva dharma anatta be True?
Perhaps you should have a good understanding of Culasunnata Sutta and Mahasunnata Sutta to know the Buddha's understanding of Sunnata.
When you attain Nirodha Samapatthi you do not have the perception and feeling. So when you emerge from Nirodha Samapatthi you know that there is a state of Sunnata.
