Just one line

All of eastern philosophy (Hinduism, Buddhism, Taoism, Sufism etc ...), at its core, can be summarized in one line.

Your mind is in dysfunction and you better go fix it!

The essence of all spiritual truths can be captured in one line.

Can you operate in this world without the sense of 'me'.

Of course, in either case there is a lot of commentary, techniques etc etc. But at its core, there is only one single line. There is nothing else to intellectually understand.
