O son of Bharata, according to one’s existence under the various modes of nature, one evolves a particular kind of faith. The living being is said to be of a particular faith according to the modes he has acquired.Bhagavad-gītā 17.3
Krishna mentions sacred texts at the end of the previous chapter, and this prompts Arjuna to ask for more details. What is the situation of persons who practice sacrificial rites but do not follow the prescriptions for such rites provided in the sacred texts? Arjuna frames his question in terms of the three modalities—illumination, passion, and darkness—so Krishna’s response, comprising most of this chapter, is also in these terms, constituting a further elaboration on the modalities from Chapter 14.
