I am quickly writing on this (importing others thoughts) because within the past month, this video is making the rounds on FaceBook. David Clark and Norman Geisler make the point that in Hinduism, good works is viewed as salvonic:

The Vedanta Hindus usually permit… three avenues to salvation:

1) meditation leading to intuitive consciousness,
2) good works of service,
3) and devotion to a personal God.

But the latter two are given legitimate status only grudgingly; the real path to Brahman is mystical union.

David K. Clark and Norman L. Geisler, Apologetics in the New Age: A Christian Critique of Pantheism (Eugene, OR: Wipfe and Stock, 1990), 125.

“All of us have become like one who is unclean, and all our righteous acts are like a filthy rag; we all shrivel up like a leaf, and like the wind, our iniquities sweep us away” (Isaiah 64:6, ISV).
