>From time to time I pick up a book by the Dalai Lama and read through it even though I won't be buying it. I find valuable yogic tidbits this way although a brief statement may not be enough for a book purchase.
In one of these, the Dalai Lama was asked about yogis who claimed they could fly - such as Milarepa. He said that yes it was possible but that there were five knots in the heart had to be un-knoted for the prana-vayus to flow properly. Here it is significant to note that the yoga-sadhanas of Naropa and Maitripa have detailed knowledge-practices (Tsa-Lung) for clearing all the prana-nadis. Note also that contemporary Tibetan practitioners have mastered both tsa-lung and tummo inner-fire and have demonstrated this empirically in deadly cold conditions which are impossible for ordinary human bodies to tolerate. However, we might also note that not one of them has demonstrated the ability to perform yogic flying (akasha gamana). We might also note that the Tibetans demand this very kind of demonstration every time some yogi says he is enlightened. Enough said?
