"A light beam emanates from every human being and reaches to the very heavens.
When two souls become one, both light beams intertwine and flow in oneness. And so, a single, yet far brighter, ray of light is created from the union of two people."
Marriage is the greatest degree of joy that human beings can find in their lives.
(Sichos Kodesh 5714, p. 245)
Based on the teachings of The Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson
A wedding is to be suffused with joy, and joy breaks through all boundaries and limitations, attaining the ultimate degree of expansiveness. This is the very antithesis of frugality.
(Igros Kodesh, Vol. XVII, p. 306)
