| Acharya Sushruta has stated that, Nidra originates from maya of devata Vishnu (विष्णुः). Thus, nidra is said to be Vaishnavi (वैष्णवी).<ref>Sushruta Samhita ([https://niimh.nic.in/ebooks/esushruta/?mod=read&h=vaiShNav Sharirasthanam Adhyayam 4 Sutram 33])</ref> As per Hindu tradition, Brahma, Vishnu and Shiva are the 3 devatas (देवताः) which represent the 3 dimensions of cosmic energy, creation, sustenance and destruction respectively. In this, Vishnu devata sustains the creation and represents the eternal principle of preservation. Thus, with respect to the human body, Vaishnavi Nidra is said to be the one that sustains life and helps in energy preservation. Therefore while evaluating the energy dynamics of human body Ayurveda lays high emphasis on sleep disturbances of the individual. | | Acharya Sushruta has stated that, Nidra originates from maya of devata Vishnu (विष्णुः).
