I can`t seem to grasp the concept of shielding effect. In inert pair effect the `s electrons are held tightly due to poor shielding effect of the d block electrons. But what about the p and s electrons beneath the d electrons? Please help.

Shoelding effect is the effect or shield provided for each shell due to the attraction of the electrons of different shells to the nucleus. 
The s elctrons are tightly bounded as s orbitals are spherical shape.
