Flower in the shadow

Yesterday I went to park near to my home to have. I saw this flower and want take photo because It looks artistic however I couldn't found which flower it is. I saw this flower when I need to get some where shaded because of sun. I feel very relaxed and take deep breath when saw this flower. 
Sometimes people are need to walk in garden and take deep breath. They need to forget every bad events in their life and focus good side of the life. People need to get rid of their bad habitats and ask why "I'm  good person?" People must think about answer deeply.
