Question: Buddha talks of becoming have a cause, is dependent on something other. Like Lamp's flame and light, shadow and real object, The sun and it's aura, object and mirage.
The dependent origination generates the false 'I' which is nothing but the becoming.

Then can one conclude the cessation of becoming is also carried out by reversal of dependent origination I.e Dependent Cessation? I think that's the way!

Shadow can be ceased only when the real object is perceived, if not the shadow thinks it as real, even though it's unreal or non existing thing! Previously perceived snake was actually the rope, when the wisdom dawns upon.
This shadow is false 'I', the illusion, the non-existant thing. But only when one sees it with eyes of wisdom! Can we say that?

Some quotes of Saints have this testimony in common,

√ Cure for Pain is in Pain!\_ Rumi

√ Samudayadhamma(origination) = nirodhadhamma(cessation)\_ Buddha

I believe the becoming and cessation are two opposite sides of the same coin!

What do others have to say about this? Please don't bring here quotes of scriptures. Do we have here the seekers which can see with eyes of wisdom?
I am asking them! Others please don't bother!

Answer: 
Good question, more to the point than your first one, IMO.

Regular samsaric mind is "flat", we see things and we interpret them non-ambiguously as per our ego's convictions.

Buddha's mind is "non-flat", it's not like it doesn't interpret at all, rather it produces a solution space of all possible and plausible interpretations at once. It's not a collection of individual distinct interpretations, more like a multidimensional gradient space.

This is why it's said the Buddha's mind is indescribable, Buddha has no position on things etc.

This has been described variously in Buddhist literature as openness or vastness or groundlessness or Emptiness or suchness or ambiguity or metaphorical homelessness etc.

So it's not that you need to stop the thought and become a rock or a log, not at all. Undoing the ego is about opening up and removing the boundaries, towards the fully open Buddha-mind (Bodhi-citta).

In practice this sort of open multiperspective is actually very helpful in everyday life. It makes one a lot less prone to being stuck in a box or getting into a conflict with others. So it's not just good for enlightenment, it makes one more robust in the regular life, too.
"governed by the mind" suggest that there is one who is governed. Once you enter the 2nd refuge of the 3 jewels of Buddhism (taking refuge in the Dharma) and the teacher and the teaching as localized sources melt away, you become one with all , therefore the continued teaching and realizations do not flow from a person or from a book anymore. The whole starts teaching herself.

2+2=4 not because your mind is localized and is able to calculate. The same way, things can be happening (urge to go to the bathroom) without the mind creating a story about it. Then "you aren't going to the bathroom", but rather "the whole is going to the bathroom". There is still "going to the bathroom", but a localized mind is not required to achieve the act.

Also IMPORTANT, none of these states are black/white, on/off, etc. In most cases there are partial realizations or degrees of achievements. Once you notice the gap (between what is and what is in the mind), you can widen that gap with practice and repetition. So the functionality of the mind can be slowly/quickly, gradually/at once be transferred/tasked to work as part of the whole, rather than work for the individual. The Eightfold Path gives you specific training to work on the mind and its functionality, to slowly erode its fascination with itself. Then it becomes a tool, rather than the seat of your god.
