The members of the Krsna consciousness movement are not at all interested in so-called meditation in the Himalayas or the forest, where one will only make a show of meditation, nor are they interested in opening many schools for yoga and meditation in the cities. Rather, every member of the Krsna consciousness movement is interested in going door to door to try to convince people about the teachings of Bhagavad-gita As It Is, the teachings of Lord Caitanya. That is the purpose of the Hare Krsna movement. The members of the Krsna consciousness movement must be fully convinced that without Krsna one cannot be happy. Thus the Krsna conscious person avoids all kinds of pseudo spiritualists, transcendentalists, meditators, monists, philosophers and philanthropists.
