The yogi is able to place the candle of his awareness, or his attention, in a niche within himself,\xa0where the winds do not make the candle flame move.

That is: where a sound, or a sight, or a smell,\xa0or a taste, or a sensation on the skin does not distract him.\xa0

What is left to distract him, of course, are still his own thoughts, his memories, his plans...
And it is here that the discipline the yogi must impose upon himself becomes exquisitely difficult, and something requiring an extraordinary amount of patience.
