We will simplify the given expression step by step:

\[
\left( \frac{1}{5} \right)^2 \cdot \left( \frac{1}{5} \right)^{-4} \cdot \left( \frac{1}{5} \right)^3
\]

### Step 1: Use the property of exponents
When multiplying terms with the same base, we can add the exponents. The base here is \( \frac{1}{5} \).

So the exponents become:
\[
2 + (-4) + 3
\]

### Step 2: Simplify the exponents
\[
2 + (-4) + 3 = 1
\]

### Step 3: Rewrite the expression
The expression simplifies to:
\[
\left( \frac{1}{5} \right)^1 = \frac{1}{5}
\]

So, the simplified result is:
\[
\boxed{\frac{1}{5}}
\]
