Surya has strength in his Uttarayana (northerly) course, when he occupies his own Rasi, exaltation Rasi, Navamsh, Dreshkan, or Hora and on Sunday. In a friendly Rasi, he has medium strength. He is strong in the initial part of a Rasi; weak in the end and moderately strong in the middle. He is devoid of strengh during twilights and eclipses.

Notes: The Shad Bal of a Grah should essentially be encouraging in order, that good results are achieved.

Surya is strong in his exaltation Rasi, in Simh, in own Dreshkan, solar Hora, on Sunday, while in northern declination, while entering in a Rasi, in the middle portion of the day, in friendly Amshas and in Karm Bhava from Lagn. (Jataka Parijata Ch. II)

Candr has strength in Vrishabh and, when in her southerly course. She is strong in her Rasi, in Hora, during the night, in her own Navamsh, on Monday and in her own Dreshkan. She is said to possess medium strength in the first ten days of the bright half, exceedingly strong during the next ten days and weak during the remaining ten days. Should Candr be in the north of the Grahas, in clockwise motion around the Grahas, yuti with, or in Drishti to benefics, she gets strength. She is weak in the initial portion of a Rasi, has medium strength in the middle portion and is strong in the last part. The Full Candr is strong in all Rasis.

Notes: See Jataka Parijata, Ch. II. Candr is strong in Kark and Vrishabh, on Monday, in her own Dreshkan and Navamsh, at the end of a Rasi, when receiving a Drishti from benefics, in Bandhu Bhava in the case of a night birth and in her southerly course. The Full Moon, if not occupying any kind of Sandhis (i. e. Rasi Sandhi, Nakshatr Sandhi, Lagn Sandhi etc.), be strong and receiving a Drishti from other Grahas, makes the native a king.
