Will disciples attain enlightenment through sudden realization or gradual growth?

According to Osho, enlightenment is neither sudden nor gradual because it is not an attainment at all. The very desire to 'attain' is greed and creates time and becoming. You are already that which you seek; spirituality is recognition, a remembrance, here-now. Drop the idea of becoming—see greed’s misery and it falls by itself—and abide in your present beingness.
