Devas
<p >From a human perspective, devas share the characteristic of being invisible to the physical human eye. The presence of a deva can be detected by those humans who have opened the <a href="http://en.wikipedia.org/w/index.php?title=Divine_eye&action=edit&redlink=1" class="new" title="Divine eye (page does not exist)" >divyacakṣus</a> (Pāli: dibbacakkhu), an <a href="http://en.wikipedia.org/wiki/Abhijna" title="Abhijna" >extrasensory power</a> by which one can see beings from other planes. Their voices can also be heard by those who have cultivated divyaśrotra, a similar power of the ear.</p>
<p>
Most devas are also capable of constructing illusory forms by which they can manifest themselves to the beings of lower worlds; higher and lower devas even have to do this between each other.</p>
<p>
Devas do not require the same kind of sustenance as humans do, although the lower kinds do eat and drink. The higher sorts of deva shine with their own intrinsic luminosity.</p>
<p>
Devas are also capable of moving great distances speedily and of flying through the air, although the lower devas sometimes accomplish this through magical aids such as a flying chariot.</p>
