Hasta mudras or hand mudras are best described as hand positions or locks or seals.
Though the terminology may be new to you it is most likely that you have seen images of some of the more common mudras.
There are many hand Mudras and the particular gesture of each one is specific to channeling energy flow in a certain way.
This is an involved and fascinating study that is beyond the intention of this article.
I personally love the exploration of the energetic response of mind and body when practicing with the mudras.
In fact, I prefer not to have too much information so that I can explore with a beginners mind.
I invite you to try just 3 different hand positions for the purpose of exploring your personal experience of each mudra by following the guided session.
We might experience a sense of grounding and calming using one mudra and a more uplifting and energetic sense of another.
Notice your personal experience as you follow the guided session [here]
