Before one of least being this 'self' can discuss there being one God or more Gods (gods) one must define God. Ultimately of myself I believe there is one God as it seems there is a starting point. However, I teeter and totter at times with the definitions presented by many lines of thought as to how one should define the 'One God'.
I lean toward an Evangelical view laced with most likely Taoism and a hint of Feng Shui philosophy. However, I am a great fan of Greek mythology and have intrigue with the Poetic Eda. All those concepts of philosophy with their ideologies do come in dancing about within my mind as well as my heart, though I still offer a realization there must have been a start, a beginning, a 'One God'.
Continuing with the second question we again must define 'real'. That is a lot of fun. To understand that one just needs to recognize the interactions of one individual with another or with an environment. Some have inferred to that as practicing 'Mindfulness', which arrived to us with today's thinking through Buddhist thought.
Recognizing a moment of 'now' with pause without reflection focusing on simply the experience one ponders 'real' is in fact 'real' while it is said to be both enlightening and awakening. Sharing is at times I have discovered one may become quite giddy with such an experience. Sometimes it may be of difference being closer to 'numinous'. At task then for me of least are those following moments of pause with reflection seeking something . . . simply something more than before.
I would next think one who seeks understanding of a God or Gods most definitely is offered many avenues to venture an adventure of learning, understanding, and a bit and byte of acceptance. Again, hinting with the practice of mindfulness while offering pause one's personal foundational base regarding God or Gods must begin with recognition of 'real' with the power of 'acceptance'. That alone may be enough for any one individual needing nothing else required.
Of a personal perspective I lace that heavily with forgiveness offering understanding. Else, with and within those interactions with 'another' as well as the environment those differences may become disappointments, frustrations, and oddities of cause for disenchantment.
Once one embarks on a venture of adventure discovering for one 'self' God or Gods while seeking if there be any delineation I would ponder one must realize of significance is such that is of one 'self' firstly.
