Never consider kusang as small. It can harm you very badly. Initially you will not feel it but after some time, your mind will not be engaged in Hari-guru chintan. Whenevr you tried to visualize them in roopdayan, kusang will attack you. So always be careful. Never see unnecessary things, never listen to unnecessary talks. Remain simple, eat simple and always reliaze the presence of Hari-guru with you.
