I lean toward Buddhist contemplative practices that morph into Christian contemplation that, in turn, morph into the quiet practices of other Wisdom traditions and the many secular forms of contemplation that enrich our lives. All are part of the great, diverse Whole. All teach us to open our hearts, one sentient being to another, no "other" left behind. All promote the cultivation of awareness if practiced with that intent!
I like the broad definition of "contemplation" represented on the Tree of Contemplative Practices. Here's a link that gives more detail on the origin of the Tree. Follow it to another link where you can download a "fill-in-the-blank" tree to create a version that includes your own favorites, perhaps not on the original.
May you be happy, healthy, whole!
