According to Osho, śamaḥ (nihsaṅkalpa: absence of resolves) and nirvichara (no‑thought) are one in fulfillment—the formless void—yet differ in method. Nihsaṅkalpa is cultivated through samatva‑buddhi: even‑mindedness, stopping in the midst of dualities and dropping choices. Nirvichara unfolds through pure witnessing: observing the stream of thoughts as a detached seer. Choose the doorway matching your temperament—desire/choice‑bound or thought‑dominated.
They both end in the same inner silence: one by staying steady and not choosing, the other by calmly watching thoughts until they fade.
