This is my mantra for the whole month. And although it's easier said than done, it is quite surprising how after a group class of 120 minutes I still feel the urge to practice another two, two and a half hours on my own.
So far, the self-practice times have been the best. I felt a sort of ekagra (concentrated, one-pointed) state of mind, really focusing on the practice itself even if it's not really one-pointed because I do a variety of poses and I wouldn't deny looking around at the others what they are doing from time to time.
And the heat also helps, I believe. Soaked in sweat, sticky everywhere but 35 degrees Celsius makes the body and joints more supple. Wonder if it's just an illusion or will my practice really change and ameliorate by the end of the month? In any case, that's the goal and I'll see to it that it happens.
