It is well known that god Śiva is called Āśutoṣa (आशुतोष) - the one who is easily pleased or appeased.
Recently, I came across another epithet for Śiva - Mīḍhúṣṭama (मीढुष्टम) while going through Kāraṇāgama (कारणागम), one of the 28 Śaivāgamas.
The great goddess (Pārvatī) refers to Śiva by this name as -
ममापराधः क्षन्तव्यो मीढुष्टम नमोऽस्तु ते । त्वयि प्रसन्न जगति दुर्लभं किमु विद्यते ।।२५।।
Forgive my transgressions. Ah Meedhustam - Shiva (Meedhustam is a name of Shiva), I pay salutation to you. If you please, what is not found in the world. (25)
On searching the meaning, it was found to be -
Mīḍhúṣṭama = "the most bounteous or liberal Lord"
This epithet is similar to Āśutoṣa in some ways.
Personally, the name sounds very unique.
Some of the occurrence of this name (Mīḍhúṣṭama) I could find in the Purāṇas are:-
तदा सर्वाणि भूतानि श्रुत्वा मीढुष्टमोदितम् ॥ ६.अ॥
6. O Vidura! When all beings heard the speech of 'the most bountiful (Mīḍhúṣṭama)' god Siva, their hearts were fully satisfied, and they exclaimed - "Well done! Well done!".
मीढुष्टमाय देवाय शिपिविष्टाय ते नमः ॥ २६.अ॥
26. Obeisance to the most bounteous lord who is pervaded by rays...
मीढुष्टमायोत्तरमीढुषे नमो नमो गणानां पतये गणाय ।
16. Obeisance to Mīḍhuṣṭama (‘the most excellent one among those who bestow desired fruits’)...
The Lalitopākhyāna (Lalitā-Māhātmya) from the Brahmāṇḍa Purāṇa altogether refers Mīḍhúṣṭama as one of the names of a Rudra.
कुलालश्चेति रुद्रास्ते नवमावृतिदेवताः ॥ ३,३४.२५. अ॥
गिरिशः शिपिविष्टश्च कुंभज । मीढुष्टम इति प्रोक्ता रुद्रा दशमशालगाः ॥ ३,३४.२८ ॥
- to 28. The following are the Rudras in the tenth outer covering,
Giriśa, Śipiviṣṭa, and Mīḍhuṣṭama.
1. Is there any specific story as to why Śiva is also called Mīḍhúṣṭama (मीढुष्टम)?
2. What information is available about the Rudra named - Mīḍhúṣṭama?
