Answer: Generally, the experience of Unity in Step 4 is not a one-time event, like arriving at a final destination, and then you are just THERE -- not at first, at least. Like everything else in human development, Unity-realization stabilizes progressively.
To some degree, all states of consciousness are impacted by how you live and what you think. On the other hand, given that Unity IS your real condition, and not just another experiential state, it is certainly possible to become continuously aware of Unity. Through the Unification process -- and more importantly, as an expression of your WILL -- you can easily become accustomed to resting in Love. And you can easily grow so familiar with the condition of Love that you can return to it anytime, at will -- even in the midst of ordinary activity. Finally, to the extent that you make resting in Love your continuous activity and commitment, you WILL feel and know the Reality of Unity as your continuous condition, in and beyond all experiential states.
