Alone But Not Lonely

Alone - think of it as the combo
Of "all" and "one."
All one, one with the All.

What did the Buddhist say
When the hotdog vendor asked,
What do you want on your hotdog?
Make me one with everything, he replied.

Likewise, when I find myself alone,
I turn it around:
I am one with the All.
I try to imagine being one with everything.
That means feeling like I am (part of) everything.
Being one with the universe or
Being one with God,
What should be my focus?
Is there a difference?
Is heaven a place where everyone's mind is
Hooked up with everyone else,
Like being online but without needing computers??
