"Think Good and it Will Be Good" – What this means, says the Lubavitcher Rebbe, is that bitachon, the absolute assurance and conviction that G‑d will make things good, actually becomes the conduit and vessel which draw down and receive G‑d’s blessings. Positive thinking is not just a way to weather negative occurences, but actually makes positive results happen.
