Allow me to start by acknowledging that the Universe/God etc. cannot be captured with words. We do not know, and I think we are not meant to know. Life would be an utter bore if we knew all of the answers. The mystery is one of the reasons for our eternal striving for existence. That being said, I am only capable of putting my ideas on the table. All readers are able to pick and choose as they please, or to leave them there entirely.
I think we are here on this vibrational plane in order to learn. We are here to learn how to love. Love is the most powerful emotion that we can experience, and we are here to spread it to all other entities on this plane of existence. Spiritual leaders have preached the same message throughout history. We are all here because we are seeking to break out of the cycle of existence in the human sphere and achieve a higher consciousness that will allow us to exist on a higher rung of an infinite ladder of cosmic experiences.
Whether or not you believe in past lives is up to you, but I believe that our souls/spirits are eternal, and we may have experienced our lives or similar lives many times before. Some of you/us may believe that we are here for the first and only time, and that may be true as well, depending on your spiritual path. Others may believe that we are doomed/blessed to repeat this life over and over in a damned/beautiful eternal recurrence. No theories are foolproof, but I can promise that living a life full of love is the easiest and best way to create a better life for yourself and for all others that you come into contact with.
Love yourself. Radiate peace, love, and harmony. Love your enemies. Show kindness to those who are in need. Be gentle with those who are angry. Show compassion and empathy to those who are suffering. Sacrifice yourself for the greater good and you will truly experience “heaven” in this life or the next. Live a life of love, find peace in this chaotic existence, and teach others to do the same, and you may begin to scratch the surface of why we are here. I know I am constantly struggling to do so myself. If it was easy, everyone would do it. Fight the good fight and better yourself every day. If life is indeed meaningless, you’ll at least be creating a better experience for yourself and everyone involved. I love all of you. Onward and upward. -TRC
