Ek Nakshatra Dosh is a peculiar type of Nakshatra dosh in which we see the birth Nakshatra (lunar constellation attained by Moon on the day of birth) of two family members born just next to each other.
When two family members, born in succession (born just next to each other with no birth in the family happening in between) are born in the same birth Nakshatra, the younger of those born suffers adversely.
If both of them share the same Nakshatra pada (every Nakshatra has 4 pada of 3 degree 20 minutes each), then the health of the younger one suffers badly. If the padas are not the same and both of them share the same birth Nakshatra only (with different pada for both of them), the wealth and happiness of younger one suffers adversely.
A very important point is to note the timing of suffering for such an individual. The suffering would start, without fail, when the two natives are physically away from each other, i.e. when one decides to live away from the other. If they live together and start growing mental and emotional distance, then also the younger one starts suffering.
Example: I am posting 2 birth charts here, and those are of 2 sisters born just after the other, with no other birth taking place in between, in the family.
Elder Sibling’s Chart
For elder sibling, birth Nakshatra is ‘Magha’ in its 3rd pada.
Younger sibling’s chart
For younger sibling, birth Nakshatra is ‘Magha’ in its 4th pada.
When these sisters started living separately, younger one’s fortunes took a dive. At that time they had mutual acrimony as well, which was resorted and she shifted back to her elder sister’s vicinity to regain lost wealth and happiness.
