Sustaining sustainability is now a matter of deep interest among academics and social scientists. There is an emerging opinion that there is a definite need to add spirituality as the fourth dimension to sustainability. The current meta-analytic study examined this aspect. The study used meta-analysis to examine the relationship between spirituality and sustainability. The research conducted using R-program has meticulously followed all the established protocols and rules of thumb regarding meta-analysis. The analysis was based on 34 studies identified from a preliminary search that yielded 1131 records retrieved from various databases. The study results show that spirituality has the potential to sustain sustainability. Further research could be carried out using more studies, as literature is only emerging in this area. It is expected that the present work will trigger further research on this exciting and fecund topic.
