This is a significant difference to other Nakshatra based chakras. Most of these classical chakras depend on a zodiac of 27 Nakshatras, so they are trigonal because the number 27 has only the divisors 3 and 9.
So the presence of Abhijit plays a key role and gives rise to a rectangular Nakshatra chart composed of 4 * 7 = 28 basic fields.
The counting is clockwise. Aswini is the 6th Nakshatra in the upper row. The other Nakshatras (including Abhijit) follow in regular manner.
The picture below shows the Chakra.
It is written that the Nakshatra Padas in neighborhood to the corners are critical points and must be regarded in a special manner.
The following table gives the zodiacal positions of the corners and their corresponding neighbourhood Padas.
|Corner||Between Nakshatras||Corner Position||Pada Before||Pada After|
|Right Upper||Bharani - Krittika||26:40 Ar||23:20 - 26:40 Ari||26:40 Ari - 0:00 Tau|
|Right Lower||Aslesha - Makha||0:00 Leo||26:40 Can - 0:00 Leo||0:00 - 2:20 Leo|
|Left Lower||Vishakha - Anuradha||3:20 Sco||0:00 - 3:20 Sco||3:20 - 6:40 Sco|
|Left Upper||Sravana - Dhanishta||23:20 Cap||20:00 - 23:20 Cap||23:20 - 26:40 Cap|
There are two main opinions about the usage of Abhijit.
