Overview

You have started running Asthama Sani since Jan 2020. But the malefic effects of asthama sani would have been less due to Jupiter on your 7th house in the past. You would have seen good results since Aug 2020. Rahu moved back to your 12th house and Ketu to 6th house would have also given good fortunes since Sep 2020.
Now Jupiter is moving to your 8th house asthama sthana, which is bad news. This Jupiter transit is short lived for a period 4 and 1/2 months in Makara Rasi. The reason is Jupiter was already in Makara Rasi for 3 months between March 30, 2020 and June 30, 2020 as part of Dhanushu Rasi transit. Jupiter will be in Makara Rasi for about 2 months between Sep 15, 2021 and Nov 19, 2021 as a part of Kumba Rasi transit. Hence the Jupiter transit to Kumba Rasi on April 5, 2021 will be considered as a regular transit.

Jupiter on your 8th house will create bitter experience for the next 4 and ½ months from Nov 20, 2020. The real heat of asthama sani will get delivered in this period. You need to be careful in anything you do. You may have a sudden debacle and financial disaster in your life. You may get into legal trouble and get defamed. Reduce your expectation and try to stay at the same level that would be a great achievement for you until April 2021. You need to increase your spiritual strength to cross this testing phase.
