There are two things: India and yoga. So, India. I didn't get to see much of the country, but what I can tell you is that it took 9 hours to drive a couple hundred kilometers from Delhi to Rishikesh. Traffic is wild and includes cars, trucks, buses, tractors, motorcycles, bicycles, horse-drawn wagons, pedestrians, and cows. If you blow your nose in Delhi, you will turn the kleenex black. The people near Rishikesh were happy and friendly. The kids loved to have their picture taken and loved to ask you for chocolate.
Rishikesh is a yogic community, so there is a lot going on that deals with that and spirituality.
Which leads us to "So, yoga."
There is so much to yoga that the average westerner doesn't realize. And we covered the beginnings of much of that. There's still so far to go, of course, but it's a start. I could talk your ear off about the yamas and niyamas, metta meditation, chakras and energy, ayurveda and the constitutions, and of course reincarnation -- but at best, you might get confused and at worst, you might get angry. Sometime, when we're hanging out over a bottle of wine (except not wine, because that's not a yogic thing to do to your body), I'll get into these things and more. For now, here are some pretty pictures, in no particular order:
