The "opposing mental attitude" referred to in the previous sutra has distinct reference to the seeds or the latent tendencies as they subsist in the mental body and in the body of desire. This mental attitude has to become one of active mental meditation and one-pointed thought if the activities of the physical body are to be subjected to a like control. Much that we do is automatic and the result of long continued emotional and mental habits. Instinctively, from ancient practice and through subjection to a world of tangible forms, our physical plane activities are governed by the five hindrances. These have to be suppressed and the work of dealing with the latent seeds and with suppressing the external activities must proceed simultaneously. The steady opposition of the mental attitude deals with one; meditation which brings in the three factors of the thinker, the mind and the physical brain will take care of the other, and this must not be forgotten, otherwise theory will not become intelligent practice. This meditation process is dealt with in Book III and need not be enlarged upon here.
