I heard a recitation of the Lalita Sahasranama recently by Brahmasrī Śrījit Nampūtirī. I particularly loved the precedent to it that goes om asyasrī lalitāsahasranāma mahāmantrasya, etc. and the dhyanam, sindūrārunavigrahāṁ trinayanām, etc. The aforementioned tantri chanted it in the Kerala Brahmin shaili and it was really pleasant to the ears. I find myself repeating it to myself in that style at times.
I am not a Brahmin. I am not a brahmacāri either. If I chant those verses, will it bring bad karma upon me?
