Truth is all that is. Since there is nothing other than Truth, Truth is alone. Therefore Truth is one. Since Truth is one, Truth is united. Since Truth is united, It is in unison. It is All for One and One for All.
All doesn’t mean each. It means totality.
There is no each. Nothing is independent of Truth.
No life form is independent of Truth. Truth is one being, one existence, one life, one living.
Formless and Self-sustaining, Self-assured, Self-contained. Selfless.
Selfless Being. Selfless Mind (because there is no being without an awareness of it).
Co-operating as one because It is one.
Loving as one because there is no other.
