The Synthesis of Yoga - Sri Aurobindo Ashram

The Sacrifice and the Lord of the Sacrifice 131
the union has a threefold character. There is a union in spiritual
essence, by identity; there is a union by the indwelling of our soul
in this highest Being and Consciousness; there is a dynamic union
of likeness or oneness of nature between That and our instrumental
being here. The first is the liberation from the Ignorance
and identification with the Real and Eternal, moks.a, sāyujya,
which is the characteristic aim of the Yoga of Knowledge. The
second, the dwelling of the soul with or in the Divine, sāmīpya,
sālokya, is the intense hope of all Yoga of love and beatitude.
The third, identity in nature, likeness to the Divine, to be perfect
as That is perfect, is the high intention of all Yoga of power
and perfection or of divine works and service. The combined
completeness of the three together, founded here on a multiple
Unity of the self-manifesting Divine, is the complete result of the
integral Yoga, the goal of its triple Path and the fruit of its triple
sacrifice.
A union by identity may be ours, a liberation and change of
our substance of being into that supreme Spirit-substance, of our
consciousness into that divine Consciousness, of our soul-state
into that ecstasy of spiritual beatitude or that calm eternal bliss
of existence. A luminous indwelling in the Divine can be attained
by us secure against any fall or exile into this lower consciousness
of the darkness and the Ignorance, the soul ranging freely and
firmly in its own natural world of light and joy and freedom
and oneness. And since this is not merely to be attained in some
other existence beyond but pursued and discovered here also,
it can only be by a descent, by a bringing down of the Divine
Truth, by the establishment here of the soul’s native world of
light, joy, freedom, oneness. A union of our instrumental being
no less than of our soul and spirit must change our imperfect
nature into the very likeness and image of Divine Nature; it must
put off the blind, marred, mutilated, discordant movements of
the Ignorance and put on the inherence of that light, peace, bliss,
harmony, universality, mastery, purity, perfection; it must convert
itself into a receptacle of divine knowledge, an instrument
of divine Will-Power and Force of Being, a channel of divine
Love, Joy and Beauty. This is the transformation to be effected,
