The Manjushri , Namasangiti is considered amongst the most advanced teachings given by the Shakyamuni Buddha. It represents the pinnacle of all Shakyamuni Buddha's teachings, being a tantra of the nondual class, along with the Kalachakra Tantra. The Nama-samgiti was preached by Shakyamuni Buddha for his disciple Vajrapani and his wrathful retinue in order to lead them into buddhahood. The essence of the Nama-samgiti is that Manjushri bodhisattva is the embodiment of all knowledge. The Nama-samgiti is a short text, only circa 160 verses and a prose section.
It is a fraction of the vast Sutras such as Avatamsaka Sutra and Prajñāpāramitā Sutras or the endless ocean of tantras such as manjushri-mula-kalpa and the mountainous Hinayana teachings and sea of sundry extra-canonical works. And yet, the Nama-samgiti contains all of the Buddha's dharmas. It summarizes everything he taught. As Shakyamuni Buddha says of the Nama-samgiti, it is "the chief clarification of words".
"manjushri jnana sattva asya-paramartha-namasamgiti" (full Sanskrit title) lit. "The chanting of the names of Manjushri , the embodiment of supreme knowledge"
