This too shall pass
The mantra 'this too shall pass' has helped me through some dark days. When life seems bleak and there is no joy it helps me to remember that these feelings will pass and I will again have better days. It is also a useful reminder when I am experiencing happiness, to be present and treasure the moment as times of joy and happiness also pass and we need to recognise them when we have them. Life is full of ups and downs and we need to see it as a flowing entity to help us not get stuck at the bottom.
