“A father in eighth-century BCE India taught his over-educated son by experiment — a split fig, a glass of salt water — and drew from those experiments the sentence Indian philosophy has been unpacking ever since: tat tvam asi, "that thou art." The same texts record, without embarrassment, that this teacher was twice out-argued, once by a king and once by his own student. That honesty is why we can trust the rest.”

“Everything that exists is one substance under many names, the way all clay pots are clay — and you can demonstrate the invisible from the visible: break a fig seed, dissolve salt in water. The subtle essence you cannot see is what everything is, "and thou art it."”
