# The eternal function of the soul *The eternal function of the soul (sanatana-dharma) is devotional service to the Supreme Lord. This is not a sectarian designation but the constitutional nature of every living entity. Just as heat and light are the eternal characteristics of fire, service to Krishna is the eternal characteristic of the soul. When this service is rendered purely, without any material motivation, one achieves the highest perfection of life.* ## The Soul's Eternal Nature Is Service ![[bg/2/17]] ![[sb/1/2/6]] ## The Soul's Constitutional Position ![[cc/madhya/20/108]] ![[cc/madhya/22/107]] ## Eternal, Not Temporary ![[sb/1/2/8]] ![[bg/9/2]] ## Service to Krishna Is Natural ![[cc/madhya/19/170]] ![[bg/3/9]] ## Awakening This Dormant Function ![[sb/3/25/25]] ![[cc/madhya/22/105]] ## The Perfection of This Function ![[sb/1/5/22]] ![[bg/18/54]] ## From the Index - [[index/entries/sanatana-dharma|Sanatana-dharma]] — The eternal religion - [[index/entries/soul|Soul]] — The eternal spiritual spark - [[index/entries/devotional-service-to-supreme-lord|Devotional Service]] — The soul's function - [[index/entries/krsna-consciousness|Krishna Consciousness]] — Awakening the dormant function
