I have given a few opinions about the nature of life according to my understanding, especially those that were experiential.  One thing for sure is that our logical brain, with all of it’s ability, will not figure out the absolute one and only truth about spiritual reality;  truth is very individual.  One of my favorite passages of the Scripture comes from Ecclesiastes 12:12 which reads:  ” And further, by these my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.”  So, by experiencing the Divine instead of head knowledge only, one will be convinced beyond question of the path ahead and the significance of our life.  Without the Spirit the word is dead.  Love one another.
