About Led Practice:
Traditionally in Mysore during the week there are daily self practice classes (Mysore style) and twice a week a full led class.
In the led class the teacher mentions the name of the postures, counts the vinyasa and guides the breath.
It's a wonderful opportunity to learn the counts and get a better understanding of the alignment.
Personally I find that it really feels great to move & breathe together as a group, it always lifts the level of energy in the Shala:)
