Here is truly how you can change the world – it states in Kabbalah, if a single person truly does this they will bring the Moshiach! – in order to activate the Divine energy of the world it is similar to what the Baal Shem Tov said in heaven – heard by the Rebbe Rashab – “wherever you are, you must sacrifice your life for God and this is done through a verse of Torah” – in other words, the question is not mechanism – all the mechanisms belong to God – nothing that happens below happens if it didn’t get decided above – hence the question is only energy
