Any tool is fair game, as long as it works and seems appropriate to the situation.
Many nondual folks are familiar with contemplative prayer, visualizations, heart prayer, Christ meditation and similar forms on prayer where a receptivity to and invitation in of the soul level is the main emphasis, possibly shifting into realized selflessness in glimpses or more thoroughly.
The more common forms of prayer, those where we ask about something specific, also have their place. They are a part of any comprehensive toolbox. They can be used as in Buddhism, to ask for awakening for the benefit of all beings. This sets a clear intention, which in turn helps reorganize and align our human self with this path and may even have effects beyond that.
And of course, prayers for the health and well-being of ourselves and others have their place. Again, they help realign ourselves with that intention. And it opens our heart. It opens for a sincere well-wishing for ourselves and others. And both of those spill over into our actions.
As with visualizations, these forms of prayer may (or may not) have an effect beyond how it works on us, in how the world shows up on its own.
In either case, the effect it has on us is more than enough reason to sometimes engage in them.
They set a clear intention for ourselves. They help realign us with that intention. They open our heart. They open for sincere well-wishing for ourselves and others.
And sometimes, especially in extreme situations, they may be comforting if that is what we need.
(And if not, if we are invited into being wholeheartedly with what is coming up and we use these forms of prayers as an escape, they – and anything else we do to try to escape – are likely to not work.)
