The Sword of Wisdom

Excerpts from God Talks with Arjuna: The Bhagavad Gita
by Paramahansa Yogananda

Wisdom & practice of yoga techniques

Therefore, O Descendant of Bharata (Arjuna), arise! Take shelter in yoga, slashing with the sword of wisdom this ignorance-born doubt existing in thy heart about the Self!
—The Bhagavad Gita IV:42

Your confusion has been caused by your response to cosmic delusion and ignorance. Owing to this doubt you have not united yourself with this Supreme Spirit by a practice of yoga. O devotee, rouse yourself from the hypnosis of doubt! With the wisdom of guru-given discrimination, distinguish between the Substance and the delusive appearances. Instead of tenaciously clinging to the delusion-caused doubt, it is far easier to cling tenaciously to the yoga-discovered Divine Certainty!"

Instead of indulging in doubts about the true purposes of life and about the possibility of finding God, man should cut away his mental imperfections with the sword of wisdom from a guru; and by practice of yoga techniques, enjoy the doubt-dispelling, ever-blessed communion with God. (p.528)
