Hey midnight,
Besides the good answers you already got, i am so free to tell you my subjective point of view
Its the same for me. I believe what happens happens, and its only our resistance that makes it sometimes hard. Life is not always the same, and so are our perceptions and feelings. Its like waves that come and go.
I was born and got some good kicks in the pants, therefore the emotional ups and downs i experienced where like flood waves. Since i begun to meditate and discover all the good possible things, these waves are getting smaller and smaller, but they are still here.
Im just coming out of an emotional valley, where i forget all the good things i knew, where theres no peace within me, no silence. Then there are times where im so still inside, that it feels like the world stops.
So what i learned is, to dont give much attention to these waves - nevertheless i can see a huge progress, and the niveau of the waves is changing big times.
Hope this helps,
Pan
