"Throughout the Gita Bhagavan Sri Krishna emphasises the need of disinterested work.
Actions springing from selfish motives are regarded as the root of all evil.
They bind one down to the transmigratory world, leading from one life to another.
Actions performed without attachment are, on the other hand, described as the purifiers of soul. They lead ultimately to Jnana and thereby to Moksha".
