Buddhism does not have a belief in a supreme  being ,  or god . Instead it asks you to look inside yourself for the universal spirit or Buddha nature . By chanting " nam myoho renge kyo " you can bring this Buddha nature closer to the surface so that it starts to affect your daily life . There are many things in daily life that are difficult to cope with and Buddhism , in  general , can provide you with tools to overcome , or change , these many and various difficulties. .
