The full moon ðŸŒ• in February falls in magha nakshatra on feb 19, 2019.
When moon transits Magha nakshatra it is one of the most powerful days to Honor our ancestors and get their blessings.
This is a good day to begin the 15 day ritual that will transform your life and brings you abundance and prosperity. It will also help you get rid of negative planetary influences. 
You have to start doing this ritual on a full moon day and continue it for 15 days without missing a day until the next new moon cycle.
1. Take a hand full of Nava Dhaniyams (Mixture of 9 grains related to 9 planets available as a packet)
2. Keep the fist in front of your eyes and circle your fist around your head until you come back to the same position. Do this 9 times. You can chant the mantra for each planet in the order of Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu and Ketu during each round so by the time you finish 9 times you have chanted the mantras for all the 9 planets.
3. Once you are done, put them in a new earthen pot. if you do not have an earthen pot you can put them in a vessel filled with some mud.
4. Everyday before you go for a shower take a small cup of water in your hands and circle it around your head 9 times. You can chant a mantra for each planet in the order of Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu and Ketu during each round so by the time you finish 9 times you have chanted the mantras for all the 9 planets. Once you are done pour the water into the earthen pot.
5. Repeat step 4 for 15 days starting from full moon until the following new moon day.
6. On the last day apply turmeric and kumkum on the pot. Pray to the pot using the 9 navagraha mantras.
7. Now take the pot in your hands and circle it around your body 9 times and then take it to a river or a lake and put the pot there (if it is a earthen pot) if not you can take it to an isolated place and leave the pot there and return home.
Doing this simple ritual with utmost devotion can help you overcome all the malefic effects of planets and strengthen them in your birth chart.
There is a saying in tamil “Andathil ullathellam pinndathil ullathu” which means whatever is in the macrocosm exists in the microcosm.
So do not doubt the process, but do this for 15 days and experience a change in your life.
