user-1: When I first started to think of encouraging myself on the path I imagined that when I reach the moment of cessation that I would see and experience dharma in an all pervading way " omniscient " is this true or false ...to sum it up once reaching enlightenment there should be a connection made with some sort of unified reality.

Wrong! There's no seeing at the moment of cessation. All experiences cease. There is no arising.
Only the Buddhas attain omniscience with enlightenment. Others do not!

Connection made with some sort of unified reality.

There's no such thing called a "unified reality". But just before cessation, you will come to the understanding that all conditioned phenomena are impermanent, unsatisfactory & uncontrollable.
Read the answer given by ven.Yuttadhammo to the following question:
How does stream entry occur?

user295: At point of cessation what you understand is Dependent Arising in some form of the other. The main systematised whay this is described is:

Four Noble Truths
Dependent Origination
Conditional Relations

Also see Dependent Arising by Piya Tan and The Conditionality of Life by Nina van Gorkom.
Some teachers emphasise on the three marks of existence though from my learning these are necessary but not sufficient realisations, i.e., if you have seen the 1st glimpse of Nirvana you have also seen the three marks of existence but having seen it does not necessarily mean you have seen Nirvana. Necessary and sufficient condition being understanding of 4 Noble Truths, Dependent Arising or / and Conditional Relations at the experiential level through at this point you will have the knowledge of the three marks of existence also. [1] and also Goenka's instruction in 20 day course mentions the 1st grilms is when you see the links of depedent origination break and reform.

In the Visuddhimagga there are nine insight knowledges. In the sub-commentary written by Mahasi Sayadaw, there are 16 knowledges. And supposedly you are supposed to be able to attain nibbana by seeing anicca, dukkha, or anatta. After you get to what to what they call Sankharu – pekkha; that means “equanimity to formations.” That is the 11th insight knowledge. When you go through this knowledge - far enough - you get to a place where you will see anicca arise 4 or 5 times very, very quickly. Or dukkha arise 4 or 5 times very, quickly. Or anatta arise 4 or 5 times very, quickly. And then you have a black-out. When you come back you will see all the insight knowledges you have gone through; it will happen automatically and you have them in the right order. That’s what they call nibbana. I understand these insight knowledges all the way up to 16. That is not nibbana.
