According to Encyclopedia of Sikhism:
“True seva according to Sikh scriptures must be without desire (nishkam), guileless (nishkapat), in humility (nimarta), with purity of intention (hirda shuddh), with sincerity (chit-lae) and in utter selflessness (vichon ap gavae). Such seva for the Sikh is the doorway to dignity as well as to mukti (liberation). “If one earns merit here through seva, one will get a seat of honour in His Court hereafter.”
According to Sikh tenets, “You become like the one you serve”.
Therefore, for those who desire oneness with God, serving God and God alone is the prime way. But God in Sikhism is transcendent as well as immanent. The Transcendent One is ineffable and can only be conceived through contemplation. Service of God, therefore, only relates to the immanent aspect of God and comprises service of His creatures. Humanitarian service is thus the Sikh ideal of seva.
Sri Guru Nanak has said:
“Truth is above everything but higher still is truthful living”. Thus seva is the first step to achieve the final goal of eternal peace.
With the above ideals in mind, the idea of forming a non-political “Nishkam Sikh Welfare Council” was conceived.
