The first requirement for attaining liberation

In regard to the standard for attaining liberation, what is the first requirement? Firstly, we must turn our mind to calm abiding. And, if we achieve this, if we turn our mind to calm abiding, then we will gain incredible practice experience. However, if our mind never turns to calm abiding we will always be projecting externally, the Dharma will never be absorbed into our mind stream and we will never bring an end to samsara. Are you willing to be free of saṃsāra?
