These two pictures appeared -- separately -- in the inbox last week.
Dharma MIttra -- on the streets of NYC. Notice the straight arms and fingers; this is also the correct method in ashtanga vinyasa yoga.
Guruji -- after recovering enough to come down to the shala two weeks ago.*
*Which reminds me: Students should practice ahimsa and stop bringing sweets and chocolates to Guruji, as it will only cause a relapse. It doesn't matter how much he likes it: sugar is very bad for him.
