Yes, all of u who answered, got it right:)
ANSWER ON WHAT IS HATHA YOGA AND WHAT IS THE CONTEXT IN WHICH IT IS USED TODAY?
Here is what the book I mention below says(commentary by Sw Muktibodhananda on the Hatha Yoga Pradipika, for Bihar school): (paraphrased by me).
Ha and that are two beej mantras. Ha stands for Pranic energy, that, the mental. Usually in each of us, one predominates, like a yo-yo. When both are made to flow as one, that is hatha yoga. Yes, today, hatha yoga is regarded as just yoga that focuses on asana practice or the physical aspect of yoga, to the exclusion of the psycho-spiritual aspect of it, towards which all practice must lead.
Ha and tha may also be interchanged for prakriti and purusha. Ida and Pingala. Yin and yang. Matter and energy. In hatha, says swamiji, first the purification of the physical complex takes place.
Does Rishi Patanjali mention asana/poses in his 196 verses (some versions of his Yogasutras have 197 verses)? And if so, how many times and in what fashion?
