DeWatcher,
The vedic and post vedic works are full of promises of karma being destroyed or a person receiving immediate liberation by virtue of any number of engagements: Surrender to a bonafide guru, chanting some mantra, praying to some god, bathing in some river, fasting on some day, reading some book etc. There is not a shortage of promises of being absolved from any number of maladies.
