Words that do not come from the heart may be taken badly. Words that come from the heart, but only from an external level - or from an internal but not innermost level - are well accepted, and they indeed achieve their goal. Explaining the concept of Hakhel, however, must come from the innermost depths of the heart! Such words will certainly achieve their intended results. We must explain and clarify to the extent necessary, regarding the essence of Hakhel, how it was observed in the Holy Temple, how to become inspired to greater awe of G-d all the days of one’s life!’’
(The Rebbe, 13 Tishrei 1981)
