Which scriptures other than the Ramcharitmanas mention that during Shiva Parvati marriage ceremony Ganapaty was worshipped?

Question

In the hundredth doha of the Balakanda of Ramcharitmanas it is mentioned that Ganapaty was worshipped during the marriage of Shiva & Parvati.

मुनी अनुसासन गनपतिहि पूजेउ संभु भवानी ।
कोउ सुनी संसय करै जानी सुर अनादि जिए जानी ।।

" At the direction of the sages Sambhu and > Bhavani paid divine honours to Lord
Ganapati. Let no one be puzzled to hear this; for one should bear in mind that gods have
existed from time without beginning."

Also in Shiva Purana 2.109

Once Narada had a desire to listen to the tales of Ganesha. Brahmaji replied-
"There were various Ganeshas in different Kalpas. During the period of
'Shweta-Kalp', Ganesha was born to Shiva and Parvati, when they went > to
Kailash mountain shortly after their marriage.

■ 1) Are there any other scriptures which mention about this incident ?

■ 2) What is meant by "In Shweta kalpa Ganesh was born to Shiva and Parvati ".
Are there mentions of Ganesha being born to some other parents during any other Kalpas?

Answer 1

Actually posts are worshipped - Manu, Indra, Saptarisis, Vedvyas, Ganesh or Ganapati or Mahaganapati, Prajapati are merely posts or titles (who holds the title can be found in Puranas. Few of them are given here and here). 

Ganesh (Head of Ganas, also known as Ganapati or Mahaganapati) is the prominent post/title since beginning or Aadi kaal (hence considered as one of the Aadi Devas) and must be worshiped before any other god.

How Ganesha became 'the first deity to get worshipped in any ritual'?

As per Shiva Purana, Lord Ganesha became (got the title) Ganapati/Vighneshwar soon after his head was severed by Lord Shiva as demanded by Goddess Parvati.

As per Varaha Purana,

Lord Brahma appeared and requested Lord Shiva by saying-

'You should make this divine child, who has manifested from your mouth, the lord of all these Vinayakas. Thus lord Shiva made Ganesh the lord of all the Vinayakas and blessed him- You will be the first deity to get worshipped in any ritual.'

As stories are from different different Kalpas, so there are many stories related to Lord Ganesha's birth and how he became 'the first deity to get worshipped in any ritual'. But above two are most famous.

Goddess Lakshmi emerged from Samudra Manthan (Ocean-Churning) but if someone conclude from this that there was no Goddess Lakshmi before that then it's not right. Because earlier than this Goddess Lakshmi was daughter of Khyati and Bhrigu. After Indra showed disrespect to her (or sage Durvasa in some stories), she made her abode in the abysmal depth of the sea and later emerged during Samudra Manthan.

Maitreya says - "O sage! It is heard that Lakshmi was produced from Ksheersagar during the churning of the sea but you say that Lakshmi was the daughter of Bhrigu and Khyati. How is it possible?"

Parashar says- "O great Brahmin! Lakshmi who never separates from the Lord is Herself eternal like Him. But still, as you have expressed your doubt, I will narrate you the real story." Read the full story from Vishnu Puran here and here

Similarly, Lord Ganesh is an avatar/incarnation of Mahaganapati. Few popular incarnations of Mahaganapati:

Source:

MahotkataVinayak- He was born in Kruta Yuga as son of Kashyap and Aditi. He killed the demons named as Devantak and Narantak.

Ganesh- He was born in Dvaapaara Yuga as the son of Parvati.

Dhumraketu- In Kali Yuga, he will be born as Dhumraketu or Dhumravarna and will destroy the Mlecchas, the sinners.

Therefore,

Lord Ganapti is Aadi Dev, he existed even before his incarnation as son of Lord Shiv and Goddess Parvati. He is there since times immemorial and hence was worshiped by Lord Shiv and Goddess Parvati at the time of their marriage.

This question is related with the below Question(s):

Is Vinayaka an individual or a position like Indra?

Which puranas contain the story of the contest between Ganesha and Kartikeya for vighnadhipatyam?

Answer 2

In Ganpati Atharvashirsh it is said त्वं ब्रह्मा त्वं विष्णुस्त्वंरुद्रस्त्वमिन्द्रस्त्वमग्निस्त्वंवायुस्त्वं सूर्यस्त्वं चन्द्रमास्त्वंब्रह्म भूर्भुवस्सुवरोम् ॥
Which means Ganesha is Brahma ,Vishnu ,Indra and all the deties ADI Shankaracharya also gave the concept of Panch-Parameshwar, which refers to as 5 aspects of Brahm(not Brahma). According to which these 5 deities are Anadi and Anant and all the deties in Santa Dharma are their incarnations or avatars. Panch Parameshwar comprises of Ganpati or Vinayak, Shiv , Vishnu , Devi or Shakti, Hiranyagarbh Brahma or Surya. According to ADI Shankaracharya there is no difference between these 5 . There is one Parameshwar, when Parameshwar does Anugrah then Parameshwar is known as Ganpati,when Parameshwar does Nigrah then Parameshwar is known as Devi , when Parameshwar does Creation then Parameshwar is known as Hiranyagarbh Brahma,when Parameshwar does Palan then Parameshwar is known as Vishnu and when Parameshwar does Sanghar then Parameshwar is known as Shiv.

In Vedas Ganpati is referred as

गणानां त्वा गणपतिं हवामहे कविं कवीनामुपमश्रवस्तमम् । ज्येष्ठराजं ब्रह्मणां ब्रह्मणस्पत आ नः शृण्वन्नूतिभिः सीद सादनम् ॥ Gannaanaam Tvaa Ganna-Patim Havaamahe Kavim Kaviinaam-Upama-Shravastamam | Jyessttha-Raajam Brahmannaam Brahmannaspata Aa Nah Shrnnvan-Uutibhih Siida Saadanam ||

Meaning: (This Mantra of Rig Veda 2.23.1 is addressed to Brihaspati / Brahmanaspati) 1: Among the Ganas (Group of Prayers), to You Who are the Ganapati (Lord of Prayers), we Offer our Sacrificial Oblations, 2: You are the Wisdom of the Wise and Uppermost in Glory, 3: You are the foremost King of the Prayers, presiding as the Lord of the Prayers (Brahmanaspati), 4: Please come to us by Listening to our Invocation and be Present in the Seat of this Sacred Sacrificial Altar (to charge our Prayers with Your Power and Wisdom). And in Various Puranas such as Brahmvaivart Puran (Ganpati khand),Mudgal Puran, Ganesh Puran and many other Vedic and Puranic documents refer him as Parabrahmparamatma.
