Meditation and contemplative practices vary from tradition to tradition and from system to system. The nature of the influence and the transformative effect of the various approaches are informed by and embedded with the goals of their religion/system of origin. As Pagans, Heathens, or whatever it may be that you call yourself, it is important to spend some time thinking about whether or not you are in alignment with techniques that have been developed within other cultural or religious streams. In some cases you may find that no significant change is needed and in others a considerable amount of adaptation will be required. This of course begs the question of the goals and outcomes of these practices. This must be determined before proceeding with the practices that you choose.
