Gevurah, the second of lower seven Sefirot, is on the left side and relates to concepts like; measurement, limitation and restraint.
Gevurah is the channel through which we direct love. Without Gevurah, we cannot set goals and make plans toward them. When we set limitations for others, especially children, it’s done out of love.
Compare this with the second habit in Stephen Covey’s classic book, “7 Habits of Highly Effective People” (Stephen Covey) which says:
“Begin with the end in mind.”
