The Motto of NSS "Not Me But You", reflects the essence of democratic living and upholds the need for self-less service. NSS helps the students to develop appreciation to other person's point of view and also show consideration to 'other living beings. The philosophy of the NSS is well reflected in this motto, which underlines on the belief that the welfare of an individual is ultimately dependent on the welfare of the society on the whole and therefore, the NSS volunteers shall strive for the well-being of the society. Therefore, it should be the aim of the NSS to demonstrate this motto in its day-to-day programme. The fundamental principle of the NSS programme is that it is organised by the students themselves, and both students and teachers through their combined participation in community service, get a sense of involvement in the tasks of nation building.
Under the National Service Scheme Technical cell, Kerala, two units are registered in Vijnan Institute of Science and Technology, Elanji with a strength of 200 volunteers. The NSS Unit aims at instilling discipline, building character, promotion of physical fitness and development of culture in volunteer’s personality through the community service.
The NSS activities such as special camp, blood donations camps, Independence Day celebration and various awareness programmes for students and the public, etc. are conducted by the NSS units of VISAT in each academic year. It provides a variety of learning experiences which must develop a sense of participation, service and achievement among the volunteers.
