How to reconcile 'You are already enlightened. There's no need to strive!' with 'You should strive for enlightenment. Purify your mind!'

There are some teachings that go along the lines of: 'You are already enlightened. You just need to realize it. Actually there's no need for you to do anything. If you try to strive for enlightenment you just end up falling into the trap of dualism. Samsara, Nirvana, treat it all like a dream' On the other hand, there are teachings which are like this: 'Work hard to rid your mind from its negative qualities, ignorance, greed, delusion. Do this practice. Purify your mind. Abandon worldly attachment. Also please do this sadhana everyday if not you break your empowerment vows and fall into vajra hell' How to reconcile this dichotomy? Is asking this question even necessary? I am aware that asking this question is inherently dualistic, and that these views don't necessarily contradict because the first is an expression of the truth at the ultimate level, while the second is the conventional level. For someone whose mind isn't at the level to embody the first view, should I continue practicing? Or am I missing something entirely?
