According to Osho, there is no distinct 'Indian philosophy'; philosophy itself is universal. What is called 'Indian' is essentially a religious vision that knows reality by direct experience and feeling, not by empirical science or speculative thought. India’s basic contribution is seeing the whole (the holy) beyond subject-object divides, emphasizing meditation, inwardness, and lived realization over concepts.
There isn’t a special Indian philosophy; it’s mainly about knowing truth by experiencing it with your whole heart, not just by thinking.
