Wherever the word Maya occurs [In Rigveda] it is used only to signify the might or the power .
The word Maya in the Rigveda (RV) generally denotes “occult power” applicable in good sense to gods and in bad sense to demons , and may be be rendered by the English word “ craft ” having a similar double application. But is used in the sense of “ illusion ” or “show”, thus forestalling later Vedanta philosophy.
Bhakti movement is of indigenous origin, since, besides a number of devotional hymns in the Rigveda , there is a sizable volume of material in the Gita , in the santiparva of Mahabharata , as well as as in some earlier Puranas to establish its Indian origin beyond doubt.
Rigveda is the Veda of knowledge , Yajurveda is the Veda of Karma , Sama Veda is the Veda of Bhakthi and Atharva Veda is Brahma-Veda, an umbrella celebrating the Divine Presence.
