According to Osho, the navel center does not develop alongside the heart and head; it is already complete and must be uncovered, while the heart (love, sensitivity) and head (reason) are gradual developments shaped by culture and practice. Techniques therefore differ: cultivate emotion and reason, but turn inwardly to discover the ever-present navel center—the ground of buddhahood and equal being.
Your belly center is already perfect and just needs noticing, while your heart and mind grow through training.
