Moola nakshatra (மூலம்), the galactic centre
Placement: 00° 00’ to 13° 20’ of Sagittarius
Element: Air (Vayu)
The quest for stability, started at Swati ends/transforms here. Moola represents the centre piece of everything. Moola in Sanskrit means the root or the centre. It is the Black Hole (Sagittarius A) lies at the centre of our Milky Way Galaxy. A star/nakshatra is like a giant nuclear reactor, when it runs out of material it loses balance and collapses on its own by becoming a Black Hole. Swati is where it loses balance and Moola is where it collapses. But its not a bad thing like you imagine, Black hole is technically considered as a dead star but that gives life to the entire galaxy. It is the most mysterious celestial object as far as science is considered. There can be plenty of other astronomical phenomena but everything is either directly or indirectly connected to Black Hole.
Ruler: Its planetary ruler is Ketu, the planet of moksha. Moksha means free of bonds which involves radical destruction of attachments to transform to the next level. The law of nature says that you become what you consume. The more you consume something the more you transform into that thing. For ex., if you're a keen learner then you'll become a living library that others will start learning from you. Its a natural process. The same way the previous nakshatra Jyeshta represents extreme attachments, so this nakshatra represents the next level of attachment i.e., transformation. Ketu provides the stability required for the transformation. Ketu is also responsible for storing your past life karmas and releasing the ripened ones to be experienced by you in your present life (either good or bad), it’s called Prarabdha Karma.
Symbol: Its symbolism is a “tied bunch of roots”. Roots are the centre piece of a plant/tree and they're hidden from our plain sight just like a Black Hole. It brings vitality and stability to a plant/tree. Roots are also used for medicinal purposes throughout human history.
Deity: Nirriti is the ruling deity of Moola. According to puranas, She's the Goddess of destruction. She represents destruction on all levels. When you destroy something, you pave way to something else, that's the law of nature. Nirriti is like Goddess Kali, dealing with destruction of bad things and construction of good things.
Animal: Male dog. Dogs are the most favourite pet worldwide. It's the number one animal to connect well with humans. They're loyal, friendly, funny, acute, agile and aggressive if needed.
Guna: It's a sattvic nakshatra. It is the first one in the sattvic belt of nakshatras. Sattva means purity and divinity (aka free of blemishes). You may wonder why a sattvic nakhsatra is destructive. It is required to destroy all the bonds/attachments and that's why we worship Goddess Kali.
Power: It represents "Barhana Shakti". The power to destroy or the power to cause destruction.
General attributes: Moola stands for breaking and making things. So the native has to break something to make something new. Their lives will always be revolving around letting go of something in order to move to the next level (to get something new). It is a gandanta nakshatra so people born with this nakshatra usually destroy a huge karmic debt by paying back so they can move further. This asterism lies at the meeting point of tamassic and sattvic belt of nakshatras. Moving from tamas to sattva is like having an ice cream followed by a hot coffee. It needs willpower and stamina which are provided by the ruling planet and the deity. It's why these people can be bold, sarcastic, straightforward and active. They can be good at understanding the central theme of matters. It also gives material prosperity due to its aforementioned quality but needs balance to maintain the stability. Balance can be taken as grounding and giving back what you gain like a service or donation to good causes. These are general qualities, reader’s discretion is advised.
