Recall that the Tree of the Knowledge of Good and Evil is a metaphor for the first awakening of human awareness: the ability to perceive a discreet self; the ability and propensity to judge phenomena as good or bad, depending on how we think we are affected; the ability to contemplate life, death and the nature of the universe. It is, in short, the realization of ego. In its immature form, the ego only perceives separation and vulnerability, and the response is fear along with a desperate grasping for protection at any cost.
The metaphorical Tree of Life represents a maturation of awareness. It is achievement of a stage of realization that recognizes the interconnectedness and spiritual nature of life and all that is. We are no longer just isolated selves, dependent solely on our ability to protect our body and our fragile ego. We achieve a realization that we are part of something larger, something that transcends time, space and physical manifestation. We are, in fact, living sparks of the very mind of Creator/Spirit/Mind/Source, breathed full of the breath of life, the creative thrill of the universe.
The garden trees themselves are, in reality, only one. They simply represent the manifestation of all that is, the complete creative activity of C/S/M/S. They are the source and stuff of life, the universe and everything (appreciation and apologies to Douglas Adams). The two trees are not distinguished by their unique and independent natures. Rather, they are distinguished only by how we view them. Their names – Tree of the Knowledge of Good and Evil or Tree of Life – are just indicators of the level of our own spiritual maturity. Have we grown to a level of trust and comfort with our place in the universe, a place of willingness to give and to receive without fear or grasping? Do we trust that there is “that” of us that transcends birth and death, space and time? Or do we see only as much as we can through the blinders of separation and scarcity, good and bad, physical life and death?
The journey from the Tree of the Knowledge of Good and Evil to the Tree of Life is, in reality, the journey from small “s” self to capital “S” Self. Nowhere is that journey presented with more clarity than in the Upanishads, wisdom teachings attached to the Hindu Vedas that grew out of the merger of the Indo-European speaking Aryan culture and the resident culture of the Indus Valley. This merger of cultures is believed to have happened about 4,000 years ago, placing the Vedas among, if not distinguishing them definitively as the earliest of what we would call scriptures.
The relevance for those of us in the West, particularly as we move away from a spirituality based on original sin and redemption through blood sacrifice, is tremendous. Here are writings, among the earliest on spiritual reflection and experience, that discover and declare the difference between these two different levels of spiritual maturity. There is no presentation or burden of guilt, just recognition that we are born into small “s” self and that our task in life is to grow, to mature to capital “S” Self, our connection with and existence in timeless being.
We are, in truest essence, born again when we make this move between the two trees, the journey from disconnected ego to connected essential being. We achieve this step, our second birth, through renunciation of attachment to the senses – the mindless drive to chase what we think is pleasure and safety and to run from what we perceive as danger and pain. Renunciation is not separation or disengagement from these life experiences. Rather, it is to live them fully without attachment, without being driven and governed by them, recognizing their passing existence as opposed to our eternal being.
From the Isha Upanishad*:
6 Those who see all creatures in themselves
And themselves in all creatures know no fear.
7Those who see all creatures in themselves
And themselves in all creatures know no grief.
How can the multiplicity of life
Delude the one who sees its unity?
8The Self is everywhere. Bright is the Self,
Indivisible, untouched by sin, wise,
Immanent and transcendent. He it is
Who beholds the cosmos together.
From the Katha Upanishad*:
Part I  15The supreme Self is beyond name and form,
Beyond the senses, inexhaustible,
Without beginning, without end, beyond
Time, space, and causality, eternal,
Immutable. Those who realize the Self
Are forever free from the jaws of death.
Part II  2The immature run after sense pleasures
And fall into the widespread net of death.
But the wise, knowing the Self as deathless,
Seek not the changeless in the world of change.
3That through which one enjoys form, taste, smell, sound,
Touch, and sexual union is the Self.
Can there be anything not known to That
Who is the One in all? Know One, know all.
Jesus said, “Very truly, I tell you, no one can see the kingdom of God without being born from above.” (John 3: 3, NRSV). This is indeed second birth, to renounce the fear and slavery of small “s” self, and to engage our true Self, at peace, at one with all there is. Experience without fearing. Enjoy without grasping. Share without owning. Choose, practice, to be born to Self under the Tree of Life.
