As Yoga practitioners, when we start practicing yoga we experiment with different disciplines. While doing so, we might experience doubts about alignment and way to perform asanas. In this case Pincha Mayurasana.

Why Pincha in Ashtanga is different than in Hatha?
Which alignment is the correct one?

First of all, there is no “ONE AND ONLY ALIGNMENT.” 

BUT, there are different disciplines with different alignments.

Each Yoga Style has its own identity.

There is not a single, unifying, objective truth, but Different Ways to perform Pincha.

Here three different hands and arms placement:

Parallel arms and hands
Interlaced fingers
Prayer hands

How:

Place the hands on the mat, shoulders above elbows and elbows above wrists
Lower the forearm to the mat
here you can keep the forearms parallel or interlace the fingers or prayer hands.
Belly engaged, lift up the hips, walk the feet towards the arms (dolphin pose)
Press the mat away from the shoulders
Kick up, tuck or press into Pincha
