A few quotes from the Rabbi on 'Customs of Israel'
teaching that the Bar Mitzvah boy is to be brought to the synagogue accompanied by lighted candles
In Egyptian towns it is customary that on the day a boy is initiated to wearing Tefillin he is brought to the synagogue in joy and song and with lighted candles on Mondays or Thursdays, so that he may be called up to the Torah scroll - on days that the tahanun is not recited during the morning Shacharit prayer. This is also the custom in the Land of Israel.
