Selfless service or Seva is a service which is performed without any expectation of result or award for performing it. Such services can be performed to benefit other human beings or society.
The idea of selfless service (seva also sewa) is an important concept in a number of religions because God is perceived as having an interest in the well-being of others as well as oneself; serving other people is considered an essential devotional practice of indirectly serving God and living a religious life that is a benefit to others.
"Living creatures are nourished by food, and food is nourished by rain; rain itself is the water of life, which comes from selfless worship and service." - Bhagavad Gita, 3.14
