Samsara is a turning wheel and so it has momentum which draws beings in like a whirlpool, that’s why to combat it both mental and physical practice can never be passive but must be composed of active strategies; even when equanimity is appropriate to the conditions, it has an agenda of escape. Into the cycle of birth and death is woven the conventions of conversation, relationship and procreation to which are attached the expectations which are the energy manifestation of samsara. To break free of it, the beginning practitioner must exercise the effort to avoid by not engaging in conversation, and not putting themselves in those situations in the first place, by adjusting their lifestyle to one of detachment.
But the crossing to the further shore is made over the waves and currents of samsara, so use must be made of conditioned phenomena. One such example is the use of wilderness as a means to establish a peaceful state of mind. Wilderness is composed of cycles, birth and growth, decay and death, and the round of changing seasons, but it also creates peace in the human organism, so skillful use can be made of this effect to advance on the path once the preparatory protective mental conditions have been fulfilled (AN 10.99).
