The Torah reveals the essence of Yaacov and Eisev through the following verse (Bereishis 25:27): "And Eisev became a man who knew hunting, a man of the field; whereas Yaacov was a pure man who dwelt in tents." It is interesting to note that this description, that contrasts the two brothers, mentions nothing of their specific actions. What’s more, it mentions nothing of Yaacov’s spirituality, i.e., his wisdom, his devotion, his good deeds.
Our sages explain the phrase Yaacov was a pure man who dwelt in tents to mean that Yaacov was a seeker of HaShem. He thirsted to come close to HaShem. His great desire to know HaShem was the genesis of all Yaacov’s purity, knowledge, kindness, and holiness. Once the desire to seek HaShem was awakened in Yaacov’s heart, it was certain that this passion would carry Yaacov to success.
Conversely, Eisev was a man who knew hunting, a man of the field, that is, a degenerate. Eisev was not involved in any worthwhile or constructive activities. He was fixated on self-indulgence, having no aspirations other then romping in the field like one of the animals. His future personality and conduct was determined by his immature ambitions.
The goals that we set for ourselves carry us to either failure or success. Eisev chose a shallow path in life. That preference caused him to lose his entire spiritual fortune.
Conversely, Yaacov wisely set his course in life to seek elevation and redemption. He knew that the pleasures of the soul are the ultimate pleasures. Therefore, he awakened his intellect to seek the eternal Creator - His Goodness and His light. The passion that burnt in Yaacov’s heart propelled him to draw close to HaShem.
May we be inspired to seek holiness by knowing our Creator, as king Solomon said, "Life is found in the light of the King’s countenance."
Implement: Ask yourself, "What did Yaacov consider as the purpose and joy of his life."
