Please keep in mind that whereas two planets in conjunction in a birth chart are physically close to each other, it is not necessarily true in a navamsha chart.
It is also true that two planets may be in conjunction in the navamsha chart but they may be physically far apart in the birth chart.
Hence analysis of conjunctions in the birth chart and in navamsha chart will have to be approached differently.
This is too little space to say more on this subject.
