I'm 47 and I've spent my whole adult life far from Jewish practice. But now I'm engaged in tshuva (i.e. returning to Judaism; lit. repentance) and I want to come back to Hashem and live my Jewish life happily, fully and completely.
Is the Bar Mitzvah a mandatory step in practicing prayers, tefillin, brakhot, and all aspects of daily spiritual life? What does it mean for an adult who did not celebrate his Bar Mitzvah? Should one be considered incomplete in some way?
Thanks in advance for your help and support!
