भक्ताय दांताय च गुह्यमेतदाख्येयमानंदकरं शिवञ्च । इदं महापातकिनां नराणां अघक्षयं वेदविदो वदंति
bhaktāya dāṃtāya ca guhyametadākhyeyamānaṃdakaraṃ śivañca | idaṃ mahāpātakināṃ narāṇāṃ aghakṣayaṃ vedavido vadaṃti
This secret teaching should be imparted to one who is devoted and self-controlled; when taught, it brings joy and auspiciousness. The knowers of the Veda declare that it destroys the sins even of men guilty of the greatest transgressions.

Sandhi Resolution Notes: गुह्यमेतदाख्येयम् = गुह्यम् + एतत् + आख्येयम्; आनंदकरं = आनन्द-करम्; शिवञ्च = शिवम् + च; अघक्षयं = अघ-क्षयम्; वदंति = वदन्ति (अनुस्वार-लेखनभेद).
The verse states that it should be taught to a bhakta (devotee) who is also dānta (self-controlled), indicating moral discipline and devotion as qualifications.
It says that the knowers of the Veda declare it to be capable of destroying sins even for those associated with mahāpātaka—major transgressions.
Spiritual knowledge is not merely informational; it is to be transmitted responsibly—only to disciplined devotees—and is presented as transformative, leading to auspiciousness and inner joy.
