This coming Shabbos would have been the first time Adelle Shayna lit candles.  She would have joined with the timeless community of Jewish women in bringing Divine Light to the world.  It is a special time-bound Mitzvah - obligated to be done at a specific time.  It is also a time-transforming Mitzvah.  Once the Shabbos Candles are lit, your home is on G-d's time.  The next twenty-five hours are set apart from the rest of the week, infused with a holiness that only comes from the extra soul brought down on Shabbos.
Our souls are our special connection to G-d.  The thread of His essence inside of each of us.  On Shabbos, that thread is doubled.  Our connection to HaShem is strengthened.  So, for these twenty five hours, we are released of our Earthly duties and bound to work for G-d.  We devote ourselves to extra prayer, extra study, and even extra food (over which we make extra blessings).  All as a means to put that extra soul to good use
Lighting Shabbos candles is the acceptance of the extra soul and the challenges it poses to you.  Can you exercise this stronger connection to G-d?  Now that you've brought more of His light into the world, can you hold it and weave it into your life?  Can you spread it?
Three year old Shiny would have lit her candle and for the first time started to contemplate the responsibilities that have rested on Jewish women for thousands of years.  Instead, she has joined our foremothers in Gan Eden.  When we light our candles this Shabbos and say our Bracha, instead of making her own Bracha, she will hear ours as it reverberates through Heaven.  Instead of drawing a single thread of Divine Light down to Earth, she will aid the connections between us and The Holy One, Blessed Be He, and send more Light down from Heaven.
