A beginner can assess a puja guide by checking which tradition it represents, who prepared or reviewed it, and which source supports its claims. Good guides distinguish public introductory knowledge from actual procedures. They state the deity and setting, identify the textual or customary basis, and separate required steps from optional regional alternatives. Exact mantras, calendar timings and temple rules should be verifiable independently.
Warning signs include anonymous quotations, invented scripture references, miracle guarantees, one “universal” method for every lineage, unqualified initiation-bound instructions or an unvalidated auspicious-time calculator. A guide's popularity, polished design or AI-generated prose does not prove religious authority. For specialized observances, use a qualified teacher or temple authority and respect health, access and safety conditions.
