Can't worship Buddha right way

In “The Transformation of Household Rituals in Mongolia: One History of Religions in a Modern Nomadistic Society” by Japanese researcher Katsuhiko TAKIZAWA, I came across an interesting observation:

An informant told me that he gave Buddha’s images, sutras and the other Buddhist tools to Gandan Monastery at the time of his father’s death in 1977, because he didn’t know how to worship Buddha right way. This mentality of “those who can’t worship Buddha right way must not have Buddha’s images” was found in many informants’ talk. This mentality often accompanies the idea of “curse”.
