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.

The simple index fund solution has been adopted as a cornerstone of investment strategy for many of the nation's pension plans operated by our giant corporations and state and local governments. Indexing is also the predominant strategy for the largest of them all, the retirement plan for federal government employees, the Federal Thrift Savings Plan (TSP). The plan has been a remarkable success, and now holds some $173 billion of assets for the benefit of our public servants and members of armed services.

My attitude about teaching has always been the same. From early on, I wanted to make yoga accessible so that anyone, regardless of ability, could experience its wonder, joy, and power. I encourage students to question, learn, and develop their own personal practice.

A minuscule 4 percent of funds produce market-beating after-tax results with a scant 0.6 percent (annual) margin of gain. The 96 percent of funds that fail to meet or beat the Vanguard 500 Index Fund lose by a wealth-destroying margin of 4.8 percent per annum.

Never underestimate the gullibility of large pools of money.

Maybe the yogi is a parent who's a little more patient with their child, or a more compassionate coworker, or an understanding boss. Perhaps, they pick up a piece of trash that wasn't theirs, turn off a light when they're not in the room, or turn off the water while they brush their teeth, sensitive to the finite nature of our worldly resources. When we become mindful this way, there's a ripple effect. We inspire others to do the same.

A yogi is one who leaves a place a little nicer than when they arrived.
