As a meditation teacher, it doesn’t help that I have to say ‘be mindful all the time’, or ‘keep the mindfulness continuous’. 

If I don’t say that, the yogis may not practice. But, it is only to try.

Yogis only need to relax and be mindful – when you lose mindfulness and you remember, then it comes back. Realize that, because you’re practicing, it comes back and you can continue to be mindful again – when you lose it, it comes back. 

Once, a yogi was getting tense from trying to make the mindfulness continuous. It was only when the yogi had the thought that the mindfulness couldn't be continuous in the beginning and he had to start from somewhere that it was such a relief to him and he could then relax. 

It’s not the continuity that comes with ‘me trying to be continuous’. Just relax and be mindful – don’t have the thought that you have to make it continuous.
