Not Christian or Jew or
Muslim, not Hindu,
Buddhist, Sufi, or Zen.
Not any religion
or cultural system. I am
not from the east
or the west, not
out of the ocean or up
from the ground, not
natural or ethereal, not
composed of elements at all.
I do not exist,
am not an entity in this
world or the next,
did not descend from
Adam and Eve or any
origin story. My place is
the placeless, a trace
of the traceless.
Neither body or soul.
I belong to the beloved,
have seen the two
worlds as one and
that one
call to and know,
first, last, outer, inner,
only that breath breathing
human being.
A: I am unattached, I am
unattached, ever free from
attachment of any kind;
I am of the nature of Existence- Consciousness – Bliss.
I am the very Self, inexhaustible
and changeless.
B: I am eternal, pure (free from
maya), liberated, formless,
indestructible and changeless.
I am of the nature of infinite bliss. I am the very Self,
inexhaustible and changeless.
C: I am pure consciousness by
nature, delighting in Self alone,
I am the nature of indivisible
bliss. I am the very Self,
inexhaustible and changeless.
D: I am the indwelling
consciousness, I am peace
beyond the universe, I am
eternal bliss by nature, I am the
very Self, inexhaustible and
changeless.
E: I am the supreme Self beyond
all matter, the supreme Shiva
beyond all cosmic appearance, I am the
very Self, inexhaustible and
changeless.
F: I am beyond all shapes
and forms. I am of the nature of
pure consciousness, never
subject to decline. I am of the
nature of contentment. I am
the very Self, inexhaustible and
changeless.
G: I am by nature the inner Ruler,
changeless, all pervading. I am
by nature the witness of
everything. I am
the very Self, inexhaustible and
changeless.
H: I am by nature without support
and yet I support all things. I
am by nature the fulfilment of
desires. I am the very Self,
inexhaustible and changeless.
I: I am beyond all mental states,
beyond all body changes. I am
the witness of all states. I am
the very Self inexhaustible and
changeless.
J: I am unattached, I am
unattached, ever free of
the nature of Existence –
Consciousness – Bliss. I am the
very Self, inexhaustible and
changeless.
