For other articles I have written on the role of Grace in liberation please see here.
I have seen that the idea that Liberation is all down to grace is often an ego-preservation strategy and excuse for the mind not to engage with the actual liberating teaching and practice.
Great sages like Sri Ramana always emphasised the need to listen to the Guru’s teaching and do the practice suggested as it is this which leads to liberation. Otherwise suffering continues indefinitely.
Teachings such as ‘no need to practice as all is already one’ and ‘no need to do anything as there is no-one to do anything’ just allow the present ignorance and suffering to continue unabated. These types of teachings give temporary relief at best, with the sense of individuality & suffering reasserting itself as the root ignorance has not been fully destroyed.
Grace is always here. Grace simply means the ever-present unchanging Self. We (the jiva or ego) must turn towards the Self to ‘activate’ Grace. The Self or Grace then does the last part by finally destroying the ego (the illusory sense of individuality), hence it is said ‘Liberation arises through Grace’, but we must turn within towards the Self first.
This is what Bhagavan Sri Ramana said again and again.
Otherwise it is just the ego-mind saying ‘all is one’, etc, etc, whilst the suffering and the sense of duality continues.
