“真言即诸天本身。智者凡以真言所作，皆由诸天而作；凡所施与，皆由诸天而施；凡所受纳，皆由诸天而纳。是故，不应无真言而受；不应无真言而行仪轨。”——如是宣说。

FAQs
Mantra is not mere sound; it is the divine presence enabling giving and receiving to become sacred and efficacious.
No specific tīrtha is referenced; the passage is a general śāstric rule on mantra and ritual validity.
Do not give or accept (dāna/pratigraha) without mantra; ritual action should be mantra-accompanied.
