Shake off selfishness. Let go of anger. Pop the bubble of pride. Accept comfort if you're grieving. If you fear, accept safety. When you have a need, let go of the idea that there is an obstacle. Throw your request onto God's desk and accept that your order is already filled. This is how to work with the angels to help yourself grow.
Do an act of Divine intervention for someone. Give something to someone for no reason. Mentally accept one new person completely, every day.
Decide that you yourself will be the first angel always, to guard and guide you, to love and cherish you, to urge you to greater freedom .... Then see what comes along, what great angels cross your path.
The angels respond to our gratitude, finding their way into our hearts and our lives, through love. Angels never miss an opportunity to be close to us. The more we thank Heaven, the more gifts Heaven will bestow.
Happiness is really only this: our consciousness of unlimited goodness. Whether we are happy for a brief moment or a lifetime or an eternity depends on how conscious of this goodness we are willing to be.
