Why: Krishna agrees the mind is indeed difficult to restrain and restless, but says it can be controlled through practice and dispassion, validating the difficulty while still insisting it's genuinely possible.
In life: being told something is hard but possible, rather than either easy or impossible, is usually the most honest and most useful framing you can receive.
Teaching: hold both halves of this answer together, yes it's genuinely hard, and yes it's genuinely achievable through repeated practice, neither half alone is the whole truth.
