Beej Mantra for Each Planet

It is said that in Kaliyuga, beej mantra gives results quickly and that is the reason we see astrologers suggesting beej mantra more often than the Vedic mantra. I personally don't believe in this theory and believe that both of the mantras are equally effective. Though this post is about Beej mantra, so here are the mantras for each planet -

Sun (Surya)
Om hram hrim hraum sah suryaya namah

Moon (Chandra)
Om shram shrim shraum sah chandraya namah

Mars (Mangal)
Om kram krim kraum sah bhaumaya namah

Mercury (Budh)
Om bram brim braum sah budhaya namah

Jupiter (Guru)
Om gram grim graum sah gurave namah

Venus (Shukra)
Om dram drim draum sah shukraya namah

Saturn (Shani)
Om pram prim praum sah shanaisharaya namah

Rahu
Om bhram bhrim bhraum sah rahave namah

Ketu
Om sram srim sraum sah ketave namah
