The Maithili Mahopanishad (Sanskrit: मैथिलीमहोपनिषद्, romanized: Maithilīmahopaniṣad) is a Sanskrit text and is one of the minor Upanishads of Hinduism describing the Videha Kingdom of King Janaka and his rule over the Mithila (region) from the ancient capital city of Janakpurdham where Lord Rama and Princess Sita was married.

[3] The Maithili Mahopanishad is among the important texts of the Ramanandi tradition.

This Upanishad is a dialogue between Sita and the Saptarishi regarding the Supreme Reality: ते होचुर्मातर्मोक्षकामैः किं जाप्यं किं प्राप्यं किं ध्येयं किं विज्ञेयमित्येतत् सर्वं नो ब्रूहि ॥

What is worth knowing for one who desires salvation?भूर्भुवः स्वः । सप्तद्वीपा वसुमती । त्रयो लोकाः । अन्तरिक्षम् । सर्वे त्वयि निवसन्ति । आमोदः । प्रमोदः । विमोदः । सम्मोदः । सर्वांस्त्वं सन्धत्से । आञ्जनेयाय ब्रह्मविद्या प्रदात्रि धात्रित्वां सर्वे वयं प्रणमामहे प्रणमामहे ॥ The sages said: In the earthly realm, the celestial space, and the heavenly realms, and in the seven continents on Earth, in the three worlds—heaven, mortal, and the netherworld.

I passed this mantra to my dear and beloved servant, Hanuman.
