I think there are many who could relate to a philosophical theory which proposes that "all are reflections of one". It's definitely interesting to have these glimpses, some even call them moments of enlightenment.. though I at least would not spend to much time on these ideas.
The moment of revelation is sufficient to trigger a shift in perception and with the help of that event, I think it's correct to assume one could draw benefits from it for a lifetime.
In contrast, spending too much time on these concepts could potentially distract and even induce unbalance. My advice would be to collect knowledge, integrate and move on. Living life's beauty to it's full potential as a human is far more important than trying to grasp the depths of the abyss.
Just my 2 cents and 10% of what I actually wanted to originally express
