Mystical prayer is essentially an experience of unity with God and God's creation. Kything is a gateway to mystical experience and can foster deeper prayer states. When you kythe you transcend separateness without losing your identity. When you kythe you enter into a state of unconditional love and spiritual union.
As a hasidic master once wrote about experiencing this spiritual energy while kything with nature:
When you walk across the fields with your mind pure and holy, then from all the stones, and all the growing things, and all animals, the sparks of their soul come out and cling to you, and then they are purified and become a holy fire in you.
~ from KYTHING: THE ART OF SPIRITUAL PRESENCE by Louis Savary and Patricia Berne
And you — what of your rushed and
useful life? Imagine setting it all down —
papers, plans, appointments, everything,
leaving only a note: "Gone to the fields
to be lovely. Be back when I'm through
with blooming".
~ Lynn Ungar, "Camas Lilies" in BREAD AND OTHER MIRACLES
You are not obliged to be beautiful
You don't have to shine.
Blooming will happen when it happens.
If you can be still for a moment
you might notice that
the roots that feed you
are still reaching silently through the dark.
~ Lynn Ungar in "November" from THESE DAYS: POEMS FOR THE PANDEMIC AGE
