Service. Offering one’s time, energy, knowledge, experience, physical labor, money, teaching, or any kind of aid or service without expectation, acknowledgement, or reward. Sevā is one of the cornerstones of Karma Yoga (the yoga of selfless service) and Bhakti Yoga (the yoga of devotion) in which selfless giving is a spiritual practice embodying the highest form of service.
In book 4, verse 34 of the Bhagavad Gītā, Kṛiṣṇa implores Arjuna to relinquish the ego and perform his duty with a sense of detachment and without regard for the fruits of his labor.
When we extend our hands in acts of compassion, the “giver” disappears, becoming instead a conduit for divine love.
