Hindi, Soft Bound Lord Caitanya teaches the science of Krishna Consciousness. That science is absolute. Dry mental speculators try to restrain themselves from material attachment, but it is generally found that the mind is too strong to be controlled and that it drags them down to sensual activities. A person in Krishna consciousness does not run this risk. One has to engage his mind and senses in Krishna Conscious activities, and Lord Caitanya teaches one how to do this in practice.
