According to Osho, both methods are right because opposites are connected and energy moves in a circle. The ‘jump’ happens from an extreme: either bring energy down from head to navel (Lao Tzu, feminine mind) or raise it from sex center to sahasrar (Yoga, masculine mind). The key is not to keep energy in the intellect; choose the extremity matching your nature—they reach the same destination.
Both roads work; pick the one that fits your temperament, and don’t park your energy in your head.
