Penedos, Peacefull nightfall

For The Sunday Challenge: what or who are you thankful for in your life

This week's theme is particularly difficult for me.
I am an atheist of Jewish origin, philosophically sceptical and culturally deeply connected to the natural elements having grown up with a healer magical grandmother who in other times would certainly have been accused of witchcraft.
I do not understand the notions of gratitude and forgiveness. For me, gratitude is punctual, it comes from an act, it is not a state. Forgiveness for me does not exist: I have a limit of understanding and acceptance, if it is exceeded the return can only come from time and forgetting, never from a voluntary act which for me would be hypocritical.
I am alive because I was brought into the world (and abandonned by my genitors), everything I can have is the fruit of my personal effort and of the experiences, help and teachings of a lifetime.There are people like my grandmother who gave me the oportunity to progress, to become a better person but I have very few pictures and it would not be actual ones anyhow. There are books I learnt a lot from too, but which to choose? No idea...
I try to be the best I can be, to learn from my mistakes and have the humility to admit them and my shortcomings.
I try to live in peace, run away from conflicts, look for nature... but nature is there, is it necessary to feel gratitude?
Didn't think I would give myself away so much here... and all because I don't know how to accomplish the theme... so I photographed what gives me peace, knowing that no barrier or chain can stop my thoughts and my ability to dream. Maybe I should be thankful to this... but who should I say thanks to ?
