Nitin: How to control negative effect of rahu & katu?
Swami Ram Swarup: Rahu and Ketu are beneficial for living beings and do not give harm. In this regard I also paste one of my answers.

In science also there are nine planets in solar system including Rahu and Ketu but their names are being recited in English.

God has created the universe and every matter has been made for the benefit of human-beings. Naturally, all the planets are of use for all living beings. There is not even a minutest matter of the universe which is useless. So, we must believe in science which also emanates from vedas. Rahu and Ketu being non-alive cannot give bad effect on our lives but a person’s deeds (good or bad) affects his life accordingly.
