Tree Pose and the Infinite
The Lord of Love is before and behind.
He extends to the right and to the left.
He extends above; he extends below.
There is no one here but the Lord of Love.
He alone is; in truth, he alone is.
Verse 12 of  of Part II of Mundaka Upanishad1
There is nothing higher than him, nothing other than him.
His infinity is beyond great and small.
In his own glory rooted, he stands and fills the cosmos.
Verse 9 of III of Shvetashvatara Upanishad1
The Infinite is above and below, before and behind, to the right and to the left.
I am all this.
The Self is above and below, before and behind, to the right and to the left.
I am all this.
Verse 25.1 of Chapter VII of Chandogya Upanishad1
Move into your own version of the Tree Pose. That is, place your leg in a position that is comfortable for you – perhaps with your toes resting on the floor, with your foot resting against your ankle, inner lower leg, inner upper leg or with your leg in the “half-lotus” position. Choose a version that will feel stable and comfortable. Bring your hands into namaste (prayer position in front of your chest). Either close your eyes (if your balance is good enough for this) or let your gaze rest on a convenient spot in your line of sight.
Spreading Roots and Branches
Imagine yourself as a healthy tree. Imagine you have strong healthy roots spreading down and sideways in to the earth and the space beyond. Imagine you have strong healthy branches spreading up and sideways into the air and into the space beyond. Imagine your branches and roots spreading infinitely through all space, into all, and connecting you to all that is. Imagine your branches and roots spreading above, below, to the front, and to the back, to the right and to the left, filling all space and connecting to all that is. Imagine your branches and roots infinitely long, infinitely dividing to form infinitely fine rootlets and branchlets – touching and connecting you with all that is. Infinitely fine rootlets and branchlets connecting, uniting you with all of infinity, all of existence. One tree, one Self, One Infinity – Oneness.
When you are ready bring your awareness back to your physical body and your standing leg and foot, connecting down into the ground. Return the foot of your bent leg back to the floor beside your other foot. Lower your arms. Pause and enjoy how you feel – then repeat the exercise with the other leg lifted into the tree pose position.
Where one realizes the indivisible unity of life,
sees nothing else, hears nothing else, knows nothing else,
that is the Infinite.
