Answer:  

	Spiritual emotion and its eightfold manifestation (ashtasattvik bhav) is an experience of non-duality with the God principle. It is not an 'emotion' experienced while doing a spiritual activity. Being a direct experience of God, spiritual emotion is a function of a high spiritual level.
	Tears of emotion are a manifestation of psychological emotion. Thus, though this manifestation may be experienced during a spiritual activity, it is still psychological in origin. Seekers, who are emotional by nature, would naturally experience such manifestations more frequently than others do.
	A seeker in the initial stages could easily get confused between spiritual and psychological emotion. Thus, he may mistake manifestations of psychological emotion to be spiritual and encourage them. In Spirituality spiritual emotion is important, while psychological emotion is discouraged. Hence, it is best not to pay attention to experiences, such as tears, hair standing, etc. One should instead focus on spiritual practice and increasing one's faith, as that would progressively lead to higher level spiritual experiences like Bliss and spiritual emotion.
