FAQs
It stresses that spiritual practice must be grounded in śāstric correctness: a mantra that is structurally “broken” (bhedita) is not merely ineffective, but can produce obstructed or distressing outcomes, so discernment and proper transmission are essential.
By implication, it teaches that devotion is strengthened—not replaced—by right method: a sincere bhakta should rely on a properly received and correctly formed mantra rather than improvising ritual elements that distort the practice.
