My third step in the golu has the ten avatars of Vishnu. These avatars are supposed to follow the order of evolution. Matsya, the fish, kurma - the tortoise, Varaha- the boar, Narasimha-half man half lion, Vamana- the dwarf, Parasurama-the angry man, Rama- the ideal man, Balarama- the strong man, Krishna-the man suited for the current world and kalki-the man on the horse.
Behind the avatars is the Vishwaroopam of the vamana avatar. I love the face of this idol.
I have ranganatha sleeping on adisesha and the famous scene from ramayana where hanuman sits at a height higher than ravana. I love the whole aura of the scene.
