one single astrological remedy.

How can we correct all planets through one single astrological remedy?

Great question except that correction is needed for self and not planets.

If planets were doing something, there is scope for correction of planets. Planets are like thermometer that indicates the temperature of a sick person. The thermometer only indicates the temperature but does not cause the sickness or temperature. Remedy for planets is like treatment for the thermometer that indicates the temperature. Will that help?? No, treatment is needed to the sick individual.

Planets and the signs and houses indicate results, and any remedy for the challenges indicated by planets, signs and houses are for the native and not the planets.

The challenges are on account of weaknesses in the nature of the native indicated by the weak planets and the single remedy is to endeavour to improve one's nature in areas suggested by the weak planets, signs and houses.
