According to Osho, when artistic training dominates and spontaneity is stifled, you become a mere technician: skillful yet uncreative. Real art needs disciplined learning followed by complete forgetting so technique sinks into your marrow. Then expression flows freely, innovative and alive. Otherwise, rules imprison you and originality withers; cross-pollination revives freshness.
If you only follow the rules, your art gets stiff; learn them well, then forget them so your heart can make something new.
