Indriya is an ancient Sanskrit word which simply put is the strength to control all five senses. Indriyas are objectified desires.The Indriyas or senses have two states, static and dynamic. When the desire begins to operate, the Indriyas are put in motion which is the dynamic state. As soon as the desire is gratified, the Indriyas shrink through Tripti or satisfaction which is the static or passive state.
