The treasury, known as Lalitā Sahasranāma (LSN) is a compilation of the names of the Goddess - the feminine power inherent in all creation.
Why chant the Lalitā Sahasranāma? Chanting the LSN becomes a meditation (dhyāna) where the object of concentration takes us from the superficial level of the mind to the depths of inner repose, to eventually facilitate the “turning upon itself” of attention.  The subtle inner form of the deity is visualized to become the object of meditation, bringing the mind to its Source, the One Absolute, beyond all limited concepts.
When we invite the Sanskrit nāmas into our inner landscape, the Lalitā Sahasranāma becomes a garland of mantras, where every life experience is rendered sacred, because it can be found in the velvety folds of the chant. This kind of practice opens us to uncommon wisdom and sweetness – this is Glorious Alchemy!
