I am not an observant Jew but I was confirmed and bar mitzvahed in a reform synagogue. I want to pray for my father who passed away 10 days ago. I would like to pray several times a day or more if possible, especially for the next 20 to 30 days. I don't live anywhere near where a minyan could be assembled. I live in a remote area of Japan. I cannot read Hebrew anymore. I have an affinity for orthodox Judaism but don't practice it. I do have a Siddur from Rabbi Shneur Zalman of Liadi. Is there a prayer I can say often during the day? How often is it OK to say the Shema? What restrictions are there on saying the Shema? Thank you for reading this question.
