The author of Lal Kitab describes Saturn as a serpent and Rahu and Ketu as its head and tail respectively. As a node of moon, Rahu shall not provide adverse results so long as 4th house or moon is not afflicted. He gives good results when Mars occupies houses 3 and 12, or when Sun and Mercury are in house 3, or when he himself is posited in 4th house. Rahu further provides good results if placed together with Mercury or expected by him.

Rahu offers highly beneficial effects if placed in houses earlier than Saturn. But if it is otherwise, Saturn becomes stronger and Rahu acts as his agent. Sun provides very good results when Rahu is expected by Saturn, but Rahu gives the effects of a debilitated planet when Saturn is expected by Rahu.

Rahu gets exalted in houses 3 and 6, whereas he gets debilitated in houses 8, 9 and 11. 12th house is his 'Pakka Ghar' and he proves highly auspicious in houses 3,4 and 6. Saturn, Mercury and Ketu are his friends, whereas Sun, Mars and Venus are his enemies. Jupiter and moon are neutral to him.

If Sun and Venus are placed together in a horoscope, Rahu will generally provide adverse results. Similarly, Rahu will provide bad results if Saturn and Sun are also combined in a horoscope. Here Mars will also become Mars negative. If Ketu is placed in houses earlier than Rahu, Rahu will provide adverse results, whereas Ketu's effect would be zeroed.
