Should an extrovert who becomes introverted change their path later in life?

According to Osho, you need not switch paths; that is not how it happens. The outward-going merges with the Whole (purna/Brahman); the inward-going dissolves into the Void (shunya/nirvana). Inner and outer are two sides of one coin—drop either and both disappear, revealing the same reality. So trust the direction authentic to you; yoga or sankhya, positive or negative language, any sincere trajectory completes itself.
