In Kabbalah, we learn that each individual is born according to their specific mazal (destiny or fate) on the day and hour chosen by God to provide the new born the appropriate opportunities to advance its spiritual development and thus, achieve its life’s fulfillment and thereby, participate in Tikkun ha’Olam.
Everyone has his own specific vocation or mission in life to carry out a concrete assignment which demands fulfillment. Therein he cannot be replaced, nor can his life be repeated. Thus, everyone’s task is as unique as is his specific opportunity to implement it.
