Populating the planet and maintaining the chain of generations. These acts are grounded in the first Torah precept given to us by the Almighty in His holy Torah - the commandment to “be fruitful and multiply.” The entire Torah hinges upon this.
The Almighty created all physical beings under the sun from four elements - fire, wind, water, and earth. When these elements are in a state of equilibrium the body is healthy. When not, the body is thrown out of kilter both physically and mentally.
Being humble benefits the health. A person who pursues prestige destroys his health and ends up dying prematurely, for his life is nothing but misery and bitterness, anger and irritation. “Whoever seeks out honor, honor flees from him” (Eruvin 13b).
Our sages teach: “If a person says, 'I will sin and Yom Kippur will atone,' Yom Kippur does not atone” (Yoma 85b). In this statement, they wish to underscore the fact that Yom Kippur is like a remedy for the sick and suffering soul. It can heal.
Everybody knows that falsehood, by its very nature, is fleeting; it has no enduring substance. Hence the sages teach: “Truth endures, falsehood does not” (Shabbat 104b). In the end, the truth alone will emerge victorious.
