Infinitely good and gentle - I would not disagree with that, although those terms are maybe not very clear.
But source of everyhing? No, that's not right.
The source of everything is in your heart. It is not infinitely good and gentle. There is good and bad, knowing and misunderstanding, greed, hatred, delusion, compassion, friendliness, and a lot of stuff all mixed together. To sort that all out completely and understand it and let go of it, that is what the Buddha taught.
Mind your mind.
