It is with a deep sense of shock and grief that we heard this morning the terrible news: Rabbi Gavi and Rivky Holtzberg, dedicated directors of Chabad of Mumbai, were among those brutally murdered in the attack on the Mumbai Chabad House.

Our hearts and prayers go out to all the innocent victims and their families of the brutal attacks throughout Mumbai, India. But this one strikes way too close to home.

No glory, no financial stability

A young man is raised in Brooklyn, NY, with a deep sense of commitment and dedication to the Jewish people. He meets and marries a young woman of similar values, a daughter of a prominent Chabad family in Israel. They are learned and scholarly, perfectly primed for a life of scholarship and success in the warm embrace of their families and community. Yet they don't choose the easy route.

Motivated by the call of the Lubavitcher Rebbe - by his vision of boundless love and service - this young couple chose to go off the beaten path. They chose a life as shluchim - as emissaries of the Rebbe - to the far off city of Mumbai in India. It's not exotic - they lived in a crowded section of one of the most crowded cities on earth, unnoticed and unknown to many of their neighbors. No glory, no financial stability. But they live there for a reason: to create a bastion of love and warmth, of holiness and purity. They open their home to thousands of people, Jews from every conceivable affiliation and background - providing a meal, an embrace, a home. Every single night they served warm kosher dinners to dozens - the American businessman and the Israeli backpacker, the successful and the destitute. They provided counseling and help for people caught up in unhealthy behavior, and spiritual inspiration to the many seeking it.

And somehow, inconceivably, a place like that, people like that, are specifically targeted for attack, for terror, for murder.

There will be time to analyze the resilience of faith

I have no words, and definitely no answers.

Their son, Moshe, turned two years old today, a day on which he himself was miraculously rescued from the Chabad House by a loving nanny. A day which he will mark for the rest of his life as the yahrtzeit of both of his parents.

Today, Moshe lost his parents. Today, Runya and I - and the 4,000 other couples around the world who serve as part of the family of the Rebbe's emissaries - lost a brother and sister. Today, the Jewish people lost one of its finest and most precious treasures.

There will be time to analyze the resilience of faith. There will be time for grand words and gestures, great memorials. But today we mourn.

And today we ask of ourselves, and of each and every one of you, to emulate the shining example of Gavi and Rivky Holtzberg. To dedicate our lives a little bit more to goodness and kindness, to true and boundless love of our fellows. To take on one additional Mitzvah, so that each and every one of us, in our own way, create a personal Chabad House - a personal space of love and holiness.

We've been repeatedly asked: What can we do?

Earlier today, Rabbi Rosenberg (Rivky's father) called on all women and girls to light a Shabbat candle tonight in his daughter's merit, as we deeply believe that a little bit of light can dispel much darkness.

A fund has been created for the victims' families, for baby Moshe, as well as for the rebuilding of Chabad in Mumbai

As students make their way back to USC next week, we will together seek proper and meaningful ways to memorialize Gavi and Rivky by bringing additional light into our own community.

On a personal note, Runya and I would like to thank all of you for your thoughts and prayers, calls and emails. May we merit to celebrate many joyous occasions together, and live to see a brighter and better world.
