It is certainly a misconception by many who are vaguely aware of the meat and substance of Reformed theology, piety, and practice that we of the Reformed persuasion are lean on the area of private spiritual devotion. So you have the likes of Richard Foster, Dallas Willard, Donald Whitney, et al. filling in the demand for more "instruction" on "spiritual formation," in the hopes of accelerating sanctification.
But whereas Scripture has laid out the three means of grace, i.e., the preaching of the Word, the Sacraments, and prayer, as the ways by which God has promised to meet us, build our faith, and hence produce the gratitude that is the ground of all God-pleasing obedience, gurus of "spiritual discipline" make much of introspection and obsessive "fruit-hunting" through devices that are really extrabiblical, taking more from mysticism than the catholic Christian faith.
