You cannot restrict the values and "comply to a gaussian distribtion." However, if you mean a standard normal distribution (i.e., you are limiting the range to within four sigma of the mean) then the damage done will be minimal.
CDF[NormalDistribution[m, s], m + 4 s] -
CDF[NormalDistribution[m, s], m - 4 s] // FullSimplify
erf(2 Sqrt[2])
% // N
0.999937
filteredData = Select[RandomReal[NormalDistribution[], {1000}], -4 < # < 4 &];
Length[data]
1000

Dear experts,
Is it possible to generate random numbers b/w any two limits (say b/w
-4 & 4 ) which would comply to a gaussian distribution ?
