If a person is plagued by doubts that lead him to question his ability to fulfill his mission, he should realize that the 3rd of Tammuz liberated us from such doubts. For it was on Gimmel Tammuz that the Previous Rebbe spoke on this topic, and publicly declared that 'Hashem will be with us'; that we have the guarantee of Divine assistance, and that we are given the capabilities necessary for the fulfillment of our mission. All that success depends upon is our own will.
It is extremely fitting to utilize these days of ‘liberation’, beginning with the 3rd of Tammuz, to strengthen and encourage one another including via holding large gatherings for Jewish men, woman, and children.
Men and women must be seated separately at these gatherings, in keeping with the customs of Jewish modesty.
