Brahmastra is the personal weapon of Lord Brahma. It was created by Lord Brahma for Indra to help him conquer the three worlds.
Brahmastra has four variations according to Valmiki Ramayana .
Brahmastra :
- Which is used by Rama to kill Maricha and defeat Jayantha
- It's also used by Indrajit to kill 67 crores of vanaras
- Vishwamitra fired it against Vasishta who neutralised with his baton
- Laxman used it to kill Atikaya
Brahma's spear :
- Ravan was gifted it as a boon by Brahma which he used to defeat laxman
- He also fired against Rama in their final encounter . Rama was gifted the spear of Brahma through mitali to counter the weapon
There is also the variation of Brahma's asura weapon named Tamasa which Ravan invoked in final war and killed crores of vanaras and vanquished every vanara cheifs except Hanuman
The final variation of infallible Brahma weapon was created by Lord Brahma . It constitutated the power of the entire universe and gods and made a universal alarm
- It was created from five elements of the universe and weighed as much as Mandhara mountain . It also possessed the form of Yama in the tip and Garuda in the feathers . It was able to tear the heart of Ravana and kill him instantly
Brahmastra power deteriorated over the course of yugas due to lesser spiritual power of humans and it wasn't that effective as used to be in Treta yuga and Satya yuga.
