The hymn, Sri Lalitambika-Sahasra-nama-Stotra, forms a part of the
instructions Bhagawan Hayagriva communicated to Maharshi Agastya. The
hymn is given in the Brahmanda-puruna and is used in the ceremony
honoring Sri Vidya and as an independent spiritual practice for
attaining the four objectives of human life. If Sri
Lalitambika-Sahasra-nama-Stotra recitation and the Sri
Lalita-sahasranamavalih worship are performed, then the ceremony
honoring Sri Vidya is effective and the rewards include curing all
diseases and increasing all wealth, but the main purpose is the
attainment of beatitude.

Sri Lalita-sahasranamavalih is the list of 1000 names from the
Lalita-sahasranama, describing her various forms, aspects and
functions. It is in honor of the Goddess Lalita Ambika. Lalita means
the playful one. Her play is creation and the functions of the
universal energy. Ambika means the mother, the one who sustains.

This text depicts the external and internal beauty of Lalita. As one
starts internalizing the process, one begins to see the beauty within
oneself and then the entire external world becomes beautiful as well.
The Sahasranama also talks about the Goddess in the form of Sri Chakra
or Sri Vidya and as Kundalini, the energy within.
