The objective of this thesis is to investigate the multivariant levels of interpretation within selected Caryās. The Caryās selected depict Buddha Nature as it was understood in tāntric Buddhism in the area of Bengal. There are three levels of interpretation. The first level is the blatant meaning, and is outlined in the translation section of the songs. The second level is the anuyoga/Mother tāntra meaning. A comparison is made between the interpretations of selected scholars. The final level is the Mahāmudra meaning. This level is inferred from various textual sources.
