Sweet,
Solitary, and Serene is Forest Bliss :-)

The forest Bhikkhu pays much
attention to the experience of the forest. He thereby enters the even
deeper, yet unattained depths of concentration. By living
thus remote, he is not distracted by any flimsy
unsuitable phenomena. He is free from
all anxiety, & stress. He thus abandons attachment to life itself!
He enjoys a taste of this bliss of seclusion, and that silenced
mental peace. He lives secluded and apart.
Silent and remote abodes delight his heart. The hermit that in
the woods can dwell alone, may gain this
sweet serene joy as well, which sublime taste is beyond the
royal bliss even in any divine paradise...
So does the forest delight any wise man
stilled
by this subtle ease of his fine forest dwelling..

ALONE
The one who sits and lives solitary,
and walks alone finds great delight in the silence of the forest...
Dhammapada story 305
SUCH ONE
The One wearing only 3 robes,
who is thin with veins exposed, who meditates
alone in the forest,
such one is a Holy One...
Dhammapada story 395
