Ashtavakra Gita
द्वैतमूलमहो दुःखं नान्य- त्तस्याऽस्ति भेषजं। दृश्यमेतन् मृषा सर्वं एकोऽहं चिद्रसोमलः॥ २-१६॥
Definitely, duality (distinction) is the fundamental reason of suffering. There is no other remedy for it other than knowing that all that is visible, is unreal, and that I am one, pure consciousness.
