I have heard of this working well for some people who have tried it.....It's making a decision to put whatever "it" is (emotions, etc.) in a safe place, to give yourself permission to put it away - which is different from suppressing it which would be more about burying it within your body hoping it never comes up - and knowing that you will get back to it. It's a mental/emotional process that can be very valuable for those that can do it....
