According to Osho, yes, taste is a sacred doorway: all experiences are God's instruments, taste too. He teaches not tastelessness but the supreme savor: eat with remembrance, offer the first bite, and feel the Beloved tasting through you. When every sense is woven with surrender, life becomes twenty-four-hour worship; food turns into prayer, and the Divine rasa is savored everywhere, including through sharing.
Yes: if you enjoy food while remembering and offering it to the Divine—feeling God tastes through you—eating becomes a simple prayer.
