Meditating is something that we can’t stop doing; we must do it always. This is the nature of meditation, cultivation.
And we might think that we can meditate part time, but since this is a practice to grow, to cultivate the good qualities of the mind, it is something we have to do all the time. Because something is happening in the mind all the time, we want to make sure that what is being cultivated is good.
And if you want the good qualities that you cultivate to not only be good, but be strong and good, then we have to do it all the time. We really have to do it all the time.
