Hanuman is the most accomplished of their lot having achieved the much- sought after eight powers:
1 ) Anima – The ability to reduce his size.
2 ) Mahima – Ability to increase his size.
3 ) Laghima – The ability to become weightless.
4 ) Garima – Ability to increase weight.
5) ) Prapti – The ability to travel anywhere and acquire anything.
6 ) Parakamya – Irresistible will power.
7 ) Vastiva – Mastery over all creatures.
8 ) Isitva – Ability to become god like with the power to create and destroy.
The Ramayana abounds with tales illustrating Hanuman’s mastery over each of these siddhas (occult powers) . Not surprisingly, he is reverently deified as a Mahsiddha (Maha=Great).
