तद्दोषपरिहारार्थं विष्णुसाहस्रकं जपेत् । ततः सुखमवाप्नोति श्रीहरेश्च प्रसादतः ॥ ७९ ॥
— Brihat Parashara Hora Shastra
Condition: Mercury in an Angle, Trine or 11th, exalted or in own sign; or conjoined the 9th or 10th lord; or in an Angle, Trine or 11th from Ketu.
Sage Parashara also describes specific configurations under which this period becomes testing — for health, relationships, wealth or work. Whether any of these apply to you depends entirely on where Mercury and Ketu sit in your individual chart. If this period is approaching or running for you, a personal reading examines these placements and, where needed, the classical remedies for them.
Sage Parashara prescribes specific remedies for this period — japa, charity and propitiation — selected according to the afflictions present in the individual chart. Because the remedy must match the affliction, the applicable remedies for your chart are shared in a personal consultation.
Phase-based timing: for an afflicted Mercury (6/8/12), the beginning brings favourable results, the middle brings comforts and gain of wealth, and the end brings distress and difficulty for spouse and children. For a weak Mercury in the Trik from Ketu, the beginning brings tremendous conflict and the middle brings pilgrimage.
A commentary note observes that when the Antardasha lord is inauspiciously placed from both the Ascendant and the Mahadasha lord, the period brings distress, conflicts and intensive struggle.
Mercury antardasha within the 7-year Ketu mahadasha lasts 11.9 months, as per the fixed Vimshottari proportions given by Sage Parashara.
Classically its tone is mixed. It gives favourable results when mercury in an angle, trine or 11th, exalted or in own sign; or conjoined the 9th or 10th lord; or in an angle, trine or 11th from ketu. The Brihat Parashara Hora Shastra also describes specific placements under which this period becomes testing — whether those apply to you can only be determined from your individual birth chart, which is examined in a personal consultation.
The Brihat Parashara Hora Shastra prescribes specific remedies — japa, charity and propitiation — for this period, chosen according to the exact afflictions present in the individual birth chart.
