The sea within!
I watched a documentary not so long ago and it got me thinking about it's meaning. It was based on an ancient Icelandic word InnSaei which has a threefold meaning, the sea within (emotions), to see within (awareness) and those potentially bring us to action, perhaps it is to change our old patterns and surrender to a Higher power. This is to see within our sea of emotions. I noticed how it was present in many teachings across many cultures.
We all have a sea within us. The emotional landscape of who we are and what we feel. The deep darkness and shadows of those feelings and the light softness of it.
"Unless you know the basic mechanics behind the workings of the ego,
you won't recognize it,
and it will trick you into identifying with it again and again.
This means it takes you over,
an imposter pretending to be you."
