What is the growing emphasis within Vaishnavism and Shaivism?

Emphasis on love and devotion to chosen deities

The concept of a savior wasn't exclusive to Buddhism. Analogous ideas were nurtured in various guises within traditions now encompassed by Hinduism. This is evident in Vaishnavism, wherein Vishnu held paramount reverence as the principal deity, and in Shaivism, where Shiva assumed the role of the supreme god. These traditions witnessed an escalating emphasis on the veneration of a selected deity.

This form of worship established a profound connection between the devotee and the god, envisaged as one steeped in love and devotion, often termed "bhakti." This phenomenon extended across the spectrum of traditions, shaping an intricate tapestry of spiritual beliefs and practices.
