For me, a "perfect life" could be described in either Christian language or Buddhist language. In Christian language, it is to follow Christ's instructions to "be you perfect as your Father in heaven is perfect." And he wouldn't have told us to do it if we couldn't (with his help).
The Buddhist way of pointing to the same thing is often called "the good life," but is better translated as "a life dedicated to the good." It means living with four fundamental qualities: humor, dedication to goodness, effectiveness, and meticulousness. In all of life, in all aspects, we seek to eliminate suffering and cultivate joy, peace, and spiritual freedom. As we do this, we encourage and support others in doing the same.
From there, each perfect life is unique to each person. In addition to the above spiritual perspective, we also have our own unique journey, which I call the journey of our soul, connecting to our unique life purpose and making our Soul's vision for life real in the world. And it always contains elements of creativity, healing, freedom, and service in relation to particular people, animals, plants, things, social environments, and ecosystems.
I was taught very little of this, if anything, as a child. Yet all of it was within me. So my life now is very much the unfolding of wisdom from within, and not an expression of the ideas about life that I received from outside me.
