According to Imam Khomeini, how supplications life believers to higher stations?

Even in their supplications if you study the supplications of Imām Sajjad and other Immaculate Imāms, you see that they brim with advice to prepare people for higher stations, which are beyond the grasp of ordinary people. Invitation to monotheism, purification of the self, detachment the world and confiding God Almighty.
