Ryvchin said: "There's a very important concept in Jewish culture and tradition of finding the good in every dark situation and ensuring that no matter how bleak the day that we fill the world with light to overcome that."
All Australians are all being encouraged to undertake what Jewish people call a Mitzvah - an act of kindness and compassion, such as checking in on a neighbour, volunteering or spending time with family and friends.
