Laziness will stop your progress in your spiritual practice. One can be deceived by three types of laziness: the laziness of indolence, which is the wish to procrastinate; the laziness of inferiority, which is doubting your capabilities; and the laziness that is attachment to negative actions, or putting great effort into nonvirtue.
