The ancient ’urban gurus’ taught the following little bit of a lifestyle tip:

‘Greet all people with  Joy’ (Ethics of the Fathers 4:12)

And it taken on face value is an amazingly powerful teaching, greet everyone you meet with joy, with a smile with inner happiness!

But the actual grammer of this anicent text is open to a deeper interpretation:

‘Accept all of the person with joy’ - no matter who that person is, learn to truly accept every part of that person, their good points and their not so good points, just accept them as they are.

But more than this accept their whole being with joy - not just having to put up with them but embrace them as full human beings both good and bad, both physical and spiritual - with a deep sense of acceptance and joy.

another way of reading the text is this: ‘[How does one learn to] accept every person /the whole of the person? [the answer is] with joy! [through cultivating joy within yourself and within your life.]

Since only if you are truly happy with yourself that you can honestly and truly accept over people as they are - for who they are - just being them selves.
