Question
Shalom rabbi, I read a book on bitachon. It said that if a man believes in own abilities then the divine Providence will be taken away from him. I have very low self esteem. I am reprogramming my subconscious mind with a book. If I reprogram my subconscious mind, immediately my reality will change. I have difficulty understanding the divine Providence. I also have other subconscious blocks. I should change myself with certain practices like visualization. If I visualize, I visualize in the present. Am I believing my own abilities and ignoring divine Providence if I follow visualization and changing self image? I have guilt everytime I follow visualization. Should I stop changing by subconscious mind and believe in Hashem and pray to him? Or should I practice reprogramming subconscious mind and believe in Hashem at the same time. The latter is causing guilt in me. Please help me. Thank you

Question
Is chuppah an actual obligation, or just minhag? Is it biblical or rabbinic? Also is there a minimum height of the chuppah?

Question
Dear Rabbi, During the recent war I’ve seen video clips of Israeli soldiers and civilians singing and saying “Am Yisrael Chai.” It seems to be an expression of elation and triumph. What does it mean and where does it come from? Thanks
