I believe that the greatest teachers create thinking students.

When you look at the results on an after-fee, after-tax basis over reasonably long periods of time, there's almost no chance that you end up beating the index fund.

Millions of mutual-fund investors sleep well at night, serene in the belief that superior outcomes result from pooling funds with like-minded investors and engaging high-quality investment managers to provide professional insight. The conventional wisdom ends up hopelessly unwise, as evidence shows an overwhelming rate of failure by mutual funds to deliver on promises.

The real riches of yoga cannot be seen; they are felt and experienced from the inside out.

My first encounter with yoga was in 1969 with my older brother Doug. I was thirteen years old, and he was eighteen. He'd learned about yoga in California on a surfing trip, and when he came back to Houston, Texas, he introduced me to this new stuff he'd learned. I'll always be grateful for that positive influence at an early age.

Practicing yoga is a constant evolution. The Ashtanga system can appear very rigid, with its predetermined sequences, but actually there's great freedom within its structure. From the repetition, we learn to find depth in the minutiae of the actions and the wonder of breath and prana.

Never underestimate the gullibility of large pools of money.
