Why is Vishnu called Purushottam

Is Lord Vishnu a Brahmin?

Yagnopavit or sacred thread is worn by dwijas (Brahmins, Kshatriya, Vaishya), not just Brahmins.

यज्ञोपवितम् परमम् पवित्रम् प्रजापतेर्यत् सहजं पुरस्तात्

आयुष्यमग्रं प्रतिमुन्चशुभ्रम् यज्ञोपवितम् बलम्स्तु तेज :॥

yajñopavitam paramam pavitram prajāpateryat sahajaṃ purastāt

āyuṣyamagraṃ pratimuncaśubhram yajñopavitam balamstu teja :॥

Put on the holy thread, the supreme purifier, who was born with Brahma a long time ago and who gives long life, primacy and purity, may the sacred thread give strength and light.

It is compulsory for every dwija ​​to wear it in order to perform duties to free a person from the 3 Maharins or debts.

Shri Hari Vishnu is not a brahmin, he is above the caste or whatever is in that samsara or worldly things. He is himself the supreme Bramhan and he wears and does everything to make the same things known to his bhaktas. It's something like a fashion that needs to be popularized by an icon, so Shri Hari does it and he says 'follow me if you want moksha' so he wears all of these things so that we can benefit from what he does or in other words fulfilling our duties and becoming nivritaa or debt free.

Please note that imitation of Shri Hari does not mean that you should have 3 wives or wear all these ornaments and think that Goddess Devi Laxmi is your consort (she was and will be your mother forever) or yourself as God contemplate, but it just means doing what he does.Be humble like him, do nothing out of excitement (i.e. take his sattva, don't just copy like an imitator, understand the meaning of everything and if you really want to follow, follow Shri Rama as he is the ideal Maryada Purushottam Avatar).

You should cite sources for claiming that Vishnu wears sacred thread to set an example for his followers. (I think it's probably correct, but you should try to find a biblical basis for it.) By the way, Hinduism says nothing against polygamy; Ramas Ekapatni vrata was most unusual and outstanding in its day.

@KeshavSrinivasan polygamy is allowed in all varnas or only for kshatriyas?

Surya

I think polygamy is only practiced by brahmins and kshatriyas because when you see all the people in Vrindavana were individually married.

@ AnilKumar Brahmins were certainly allowed to take multiple wives. By the way, the Manu Smriti says that subsequent women after your first wife are allowed to have lower and lower castes (while your first wife should always be of the same caste). The Anushasana Parva says that if a Brahmin has four wives from the four castes, his property should be divided from the highest to the lowest caste in a ratio of 40% - 30% - 20% - 10% after his death: holy-texts.com/ hin / m13 / m13b012.htm

@Surya The Anushasana Parva chapter I linked to says that Vaishyas should only take one wife, but that some Vaishyas ignore this and take a second wife from the fourth caste. In this case, the property should be divided between 80% - 20%.
