Garudasana means Eagle posture, it´s also the name of the king of the birds.
The vehicle of Visnu.
The asana develops the ankles and remove stiffness in the shoulders. This is why it can be effective in cases of “muscle-contraction headaches” because it can release the muscle-tension in critical areas around the neck, shoulders and chest.
It´s also good if you want to have access to your lower back and buttocks without the tension created in case you have “short” hamstrings.
Be careful if you have any shoulder injury, more specific: rotator cuff problems. And remember, in case you have any specific condition go out there and find a good teacher that, I´m sure, will be happy to guide and help you.
Personally, one of the things I like more about this posture is that I find it one of the most mysterious ones between the standing postures.
Daniel took the photo without knowing anything about the meaning of it´s name. And three little birds are there with me, singing sweets songs. Synchrony is cool, isn´t it?
