Shivaya Subramuniyaswami

You can't explain It.
You are only able to feel Its existence
if your senses are sufficiently purified for this,
but you cannot explain It.

To know Him, you must experience unity with Him.
And the best thing you can say when describing It
is that It is the depth of your Being,
your core.

He is you. Here's how you can mentally imagine It:
there is emptiness above you;
there is emptiness under you;
to your right is emptiness;
to your left is emptiness;
