स्वप्नमन्त्रलाभन्यायः
This maxim takes its origin from the fact that a mantra in order that it may secure success to a worshipper must be obtained not in a dream but from a guru or a preceptor, who has himself attained success, and is used to denote that to be able to attain success in any undertaking one must submit himself to the guidance of an experienced teacher.
