Let’s look at important things here –
Jupiter - It is the most benefic planet and it represents all the auspicious things like Knowledge, Wisdom, Law, Guru, Spirituality, Religion, Philosophy, Literature, Elderly People and Children etc. For a girl, Jupiter also represents Husband.
Krittika - It is nakshatra of criticism, cutting things, surgeries and bloodshed. Also, it is nakshatra of child care, secrecy, research, protection and foster parenting etc. It spreads from Aries to Taurus. It is ruled by Sun.

Aries – As Krittika is part of Aries, Aries sign and its representations become important here. Aries is the 1st sign of zodiac belt, so it represents the things and energy of 1st house of horoscope like Self, Personality etc. Besides that, Aries is the sign of our individuality, our aggression, our actions, our competitive ability etc. Aries is ruled by Mars and it is consisted of 2 and half Nakshatras named Ashwini, Bharani and Krittika.
Taurus - As Krittika is also a part of Taurus, Taurus sign and its representations become important here. Taurus is the 2nd sign of zodiac belt, so it represents many things related with 2nd house of horoscope like, Hoarded Wealth, Assets, Savings, Finances, Luxuries and Liquid Money. All in all a sign related with luxuries and all the conveniences of life. Taurus is consisted of 2 and half Nakshatras, i.e. Krittika, Rohini and Mrigshira. Taurus' lord is Venus.
Mars – As Mars rules Aries, Mars’ position and dignity is important to know about the overall functioning of any planet in Krittika/Aries.
Venus – As Venus rules Taurus, Venus’ position and dignity is important to know about the overall functioning of any planet in Krittika/Taurus.
Sun – Likewise as Sun rules Krittika, Sun's position and dignity is important to know about the overall functioning of any planet in Krittika.
Houses Involved – Also, we can’t afford to forget the houses involved as a planet can be ruling different houses and sitting in different house for every person as per ascendant and planet’s position. To know overall affect, we have to consider the houses involved as those areas of life are being impacted.
Interpretation of Jupiter in Krittika Nakshatra – Now, Jupiter is in Krittika Nakshatra which is ruled by Sun. Dignity-wise, Jupiter is strong in Aries section of Krittika as it is in sign and nakshatra of friend. In Taurus section, it will lose sign based dignity as it is in enemy sign. As Krittika is nakshatra of nurturing and taking care of others without any selfish means, Jupiter here can become a teacher or guide who is selflessly sharing his knowledge with others and takes care of others through knowledge and wisdom. At the same time, Krittika's lord Sun and Aries' lord Mars are both fiery which can make these people rigid or fundamentalist about their knowledge and beliefs. They can be very good at analyzing and criticizing things or people as Krittika is nakshatra of critics. They can have good knowledge of child care. They can also be teachers in military skills and weaponry. In Taurus section, they may apply the same knowledge in matters of wealth, assets and financial matters. As Jupiter expands things, they can be very wealthy when Jupiter is in Taurus section of Krittika.
As Krittika is nakshatra of sharp weapons and cutting things, in relationship matters, they can suffer due to uttering unnecessary words which can hurt ego of partner and can bring ego clashes or aggression in relationship. It is more so in Taurus section, where Jupiter is losing its dignity. So, they need to be careful to avoid ego clashes in relationship matters.
Role of Mars – Mars's position will become important in functioning and results of Jupiter in Krittika/Aries as Mars rules Aries.
Role of Venus – Likewise, Venus's position will become important in functioning and results of Jupiter in Krittika/Taurus as Venus rules Taurus.
Role of Sun - As Sun rules Krittika, its position is also important to finally decide about the results of Jupiter in Krittika.
Other Factors – And of course, we need to consider conjunction, aspects, house lordship, house position and dashas etc to know the exact results of Jupiter in Krittika in either of the signs. So, we always need to take a holistic view of chart rather than just 1 planetary position.
Conclusion – So, this is how I see Jupiter in Krittika can work in a chart.
Hope this helps. Please post any comment or query you may have.
