 Advaita is also thought to strongly diverge from solipsism in that, the former is a system of exploration of one's mind in order to finally understand the nature of the self and attain complete knowledge.The unity of existence is said to be directly experienced and understood at the end as a part of complete knowledge.On the other hand, solipsism posits the non-existence of the external world right at the beginning, and says that no further inquiry is possible.
