The Lonely Saint painting, on the other hand, is quite special... standard & ordinary in most elements,
but with the rare and delightful motif of a bird (magpie, i guess) holding-up one of his extremely-long
eyebrows
(or catching it to eat, thinking that it's a white worm?) while the other one is hung over a top-crook
of his staff.  This has been seen before, in Long-Eyebrow Arahant icons, rarely in a Dokseong.
Samseong-gak
and the Lower View-Crags
at the rear of the Inwang-sa Complex,  on Inwang-san
This simple shrine, otherwise nameless, serves as the main Samseong-gak  [Three Spirits or Saints Shrine]  for
the entire "Inwang-sa" complex at its rear.  It is perched on a boulder-platform just 20 meters behind
Seon-bawi,
at the far foot of
the Benevolent King Crag;  the Tiger Crag can be seen also looming over it on its right in both of
the above photos.   A room where the caretaker, seemingly an independent shaman, sleeps is on the right side,
and also (gray) a guest-room / storage-hut.   A sacred three-trunked-tree
(appropriate!) stands in-front;  note the
bottles of
makkeoli rice-wine placed at its base in supplication.

It is usually busy with worshippers and meditators of all sorts; many of them leave offerings of food and liquor.   
Steep steps to the left of it lead up to the Lower View-Crags (below), and further up to the
Upper Stone Altars.
Signboards:  "Sam-seong-gak" left,  
"
San-shin-gak" above,  "Chil-seong-gak" below.

curiously, there is no
Dokseong-gak signboard...
Inside is the typical arrangement:  Sanshin is on the right, Chilseong in the center and Dokseong is on the left.
The San-shin-do [Mountain-Spirit painting]  is quite standard and ordinary, virtually a prototype for the genre.
The Seven Stars painting (left) is so minimal and ordinary, there's nothing to say about it.
A few steep steps to the left of the Samseong-gak lead up to the Lower View-Crags, which offer
sweeping views to the south and are a crude natural shrine-site in-themselves.  This is just 30
meters directly behind and above the
Seon-bawi, but it cannot be seen from here (blocked by trees).   
Shamans sometimes sit up here all night long, with the downtown lights below them, supplicating
the spirits with prayers, chanting & drumming by candlelight.   The simple stairs-trail continues
further around the left side, up to the Upper View-Crags and then up to the
Upper Stone Altars.

plenty of candle-wax can be seen in the female-ish cleft
