I saw the connection of the word “WELLBEING” (or “WELL-BEING”) as being opposite to or in contrast to “EXISTENTIAL UNHAPPINESS”. Happiness in general does lift one's wellbeing to an extent, but it does not equate fully to lasting wellbeing. But happiness manifested in existential form does sustain wellbeing fully. Wellbeing is fully alive when it shows up as "existential happiness".
Rupert Spira in his book “The Nature of Consciousness” pointed out that “… the recognition of the fundamental reality of consciousness is the prerequisite and a necessary and sufficient condition for an individual’s quest for lasting happiness and, at the same time, the foundation of world peace.” And that “… the overlooking, forgetting or ignoring of this reality is the root cause of both the existential unhappiness[1] that pervades and motivates most people’s lives and the wider conflicts that exist between communities and nations.”
Furthermore, “The consciousness-only model is not new. All human beings are at the deepest level essentially the same, therefore there must be a fundamental knowledge of ourselves that transcends the local, temporal conditioning that we acquire from our cultures and thus share with all humanity, irrespective of our political, religious or ideological persuasions.”
"Awareness or Consciousness is the open Unknowingness on which every experience is written." (Rupert Spira)
What is emerging for me is that self-enquiry, self-awareness, and self-realisation must be the fundamental aspects to one’s wellbeing and one’s lasting happiness at existential level. When we work on realising our full potential, the whole of person reaches out from the finite into to the infinite.
