1) does ego have a begining?
Yes, when illusion happens, ego happens. When illusion ends, ego ends. Ego is just another word for illusion.
2) does Universal Mind have a begining?
No, it's always there, beginningless and endless. When Universe ends, it's still there. Universal Mind is in fact YOU, your nature.
3) if ego does have a begining, how it come to being?
Ego is an illusion that came out of ignorance of the Universal Mind. Ego is a superimposed projection of the big Mind. Like you are sleeping in bed and you start to dream. You can dream multiple ego characters in your private dreams. But when you wake up, all these ego characters disappear. You remain as you, unchanged. Universal MIND can manifest and unmanifest at the same time. Actually there is no concept of time in pure MIND. This MIND is absolute, all transient beings came out of it. This MIND is in fact YOU, the impersonal YOU.
