Vishakha means double natured. One side is like an angel and other is the shadow side. They are extremists. They are either extremely good or extremely bad depending upon the opposite person and/or situation. Possibly Emperor Ashoka was a Vishakha male, he didn't get his mother's love when he needed and his father always hated him.
I think they go to any lengths to achieve their goals but the angel inside them takes them to the part of dharma. Also, they can make the most outstanding lovers. Despite of being the most charming and magnetic, Vishakha natives prefer monogamy or monoandry.
They fall in love just once and that is one true time. The rest relationships are switched-off by the smart mind of the Vishakha natives. They don't let any affair or frivolous person disturb the place and position of the woman they have loved with their deep heart.
Many women flock to them but they are not blinded with their charms or their praises. Unlike the men of Hasta nakshatra, Vishakha men see through the motives of each honey bee and recognize the trap. The Yoni of Vishakha males is tiger and they can be extremely selective. They can have lots of affairs and choose their lofty goals above everything. They can go without marriage.
Only a fierce woman can sustain their energy. By fierce it doesn't mean an aggressive woman. It means someone who can handle their Agni that burns after every new goal. They are expansionists. They don't stop. A dominant Moon in Vishakha nakshatra men prefer the woman whom they can respect with their heart and soul. Their standards are extremely high and it will take some legendary person to fit that role. Their love story is as legendary as their success story is.
They charm and magnetize people with their determination and high ideals. In politics they shine with their unique light and show the way to the rest of the world.
Examples of Vishakha males: Emperor Ashoka, Leonardo Di Caprio, Peshwa Vishwasrao, Napoleon 111 of France and many more.
Fictional Character: Batman and Bruce Wayne.
