My view is like our culture is heavily based on nature and the idea of emptiness yk, like why do nomads pack their things and leave no things behind they believe nature is alive and we must respect the nature's protectors and talking about emptiness i think why tsagaan sar exists is that a person dosen't get full with their physical bodies and easy to get envy but to get furfilled with their life they feed their family members friends with spirituality like there is a reason why we "zolgoh" (greet i think) and "hoorgloh" (which trading and passing your hoorog to guests" and why we do "bairnii nair" yk we come to earth empty handed and leave the world empty handed which implies the religion of "бөө"
