Sloth and the Hindrances In ven. Nyanaponika Thera's compilation, The Five Mental Hindrances and Their Conquest, some aspects seem to recur: 


One should attend to hindrances -- sloth included -- with wise attention and not unwise attention. What is meant by this?
For sloth, one should contemplate the drawbacks of sloth (e.g. meditate on death, on suffering) and on inspiring topics (e.g. sympathetic joy, spiritual journey, master's greatness). Are inspiring topics of contemplation natural remedies against sloth? If so, would being moved and experiencing awe counter sloth as well?


Such states as awe or being moved have been studied and valued in psychology, but I have never seen them opposed to laziness or lack of motivation. It just seems to me that the topics of contemplation mentioned in the Five Hindrances text most likely elicit elevation and a sense of meaning in their practitioner.
Yoniso manasikāra as such means “directing the attention to the roots of things,” that is, observing
  phenomena as they truly are, as being characterized by impermanence, unsatisfactoriness and not-self.


Yoniso Manasikāra Sampadā Sutta

You should know the experience of the hindrances are also impermanence, unsatisfactoriness and not-self.


  If so, would being moved and experiencing awe counter sloth as well?


Stimulating the mind may result in sloth on the downturn when stimulation is ending.
