If the universe is friendly, then it is indeed aware of us and works to help us. So there are no 'unfortunate accidents,' and everything that happens is orchestrated in an elaborate and complicated manner to be of benefit to us.
Unending joy is actually closer to us than our own skin, and there is nothing we have to do or get or be to experience it. All we have to do is stop driving it away.
Think of the universe as a benevolent parent. A child may want a tub of ice-cream and marshmallows, but a wise parent will give it fruits and vegetables instead. That is not what the child wants, but it is what the child needs.

I have exercises that lead participants to discover for themselves that their deepest fulfillment comes when what they're doing is of benefit to larger society in some way. This really knocks some for a loop - especially those schooled in the 'take no prisoners' approach.
Stress appears in your life because you have a rigid view of 'This is the way the world should be,' and the Universe pays scant regard to your desires. And you refuse to accept this.
