understanding "virgin birth" in sastra

[Paramananda das]

https://en.wikipedia.org/wiki/Parashara
my Gurudeva says in a lecture that sage Parasara Muni impregnated Satyavati simply by glancing at her and Srila Vyasadeva was born and she even kept her virginity after giving birth to Srila Vyasadeva.These things are impossible to understand with our blunt material senses. The Bible has two accounts of birth without sex , one is Jesus Christ being born from Virgin Mary, and then there is John the Baptist who was also born from his mother although she was in her 70th or 80th .That is also described in the Bible as being due to the internal energy of the Lord , we call Yoga Maya and the Bible call the Holy spirit. In the Old testament I do not recall virgin birth but I have no read it in many years so I could be wrong .Some say Kunti also gave birth without sexual intercourse to the 3 Pandavas. But if Kunti had been impregnated in this "mysterious fashion " then why would she be opposed to again have sex with another demigod to get children for her husband Pandu that had been cursed by a sage couple he accidentally killed while copulating ?She gave birth to Karna, Arjuna ,Yuddhisthra and Bhima .She made a statement that if she has sex one more time for having a child she would be considered a prostitute due to having sex with different men. But her pregnancies were not irreligious. but a boon given by Durvasa Muni that she could call any demigod to have a child with .So her case seems to be different . I think another thing that is bit confusing to me is , if mother Ganga is the eternal consort of Lord Krsna how could she beget children with Maharaja Santanu? Would it not seem
strange an eternal consort of the Lord ,having sex with a mortal being ?But though we may try to understand these things. There are no clear answers. But these are natural questions to ask .
