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:-
Śrīmad-Bhāgavatam Purāṇa
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!".
Śiva Purāṇa
मीढुष्टमाय देवाय शिपिविष्टाय ते नमः ॥ २६.अ॥
26. Obeisance to the most bounteous lord who is pervaded by rays...
Skanda Purāṇa
मीढुष्टमायोत्तरमीढुषे नमो नमो गणानां पतये गणाय ।
16. Obeisance to Mīḍhuṣṭama (‘the most excellent one among those who bestow desired fruits’)...
Brahmāṇḍa Purāṇa:
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.
Questions:
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?
