According to Osho, knowledge and devotion are inseparable complements. Knowledge, of the mind, clears ignorance, discriminates, and prepares the ground; devotion, of the heart, sows the seed, gives life and movement. Alone, knowledge is a clean desert; alone, devotion is blind and shaky. United (like lame eyes on strong legs), they become two wings/oars that carry one to realization, harmony, and nirvana.
Use your head to clear confusion and your heart to grow love—together they guide you safely to truth.
