The heart is the centre of the emotional being, the highest part of the vital. The navel is the centre of the dynamic and sensational vital (this is the source of pride, sense of possession, ambition, anger and other passions—but it expresses them of ten through the heart centre). <ref>http://incarnateword.in/cwsa/28/the-system-of-the-chakras#p64</ref>
=The Difference between Psychic and Emotional Being =
Emotion belongs to the higher vital, not to the pure psychic. The psychic is a steady flame that burns in you, soaring towards the Divine and carrying with it a sense of strength which breaks down all oppositions. When you are identified with it you have the feeling of the divine truth—then you cannot help feeling also that the whole world is ignorantly walking on its head with its feet in the air! <ref>https://incarnateword.in/cwm/03/the-ordinary-life-and-the-true-soul#p4</ref>

…this inmost soul, that is, the central psychic being, influences the superficial parts of the consciousness (superficial in comparison with it: mental parts, vital parts). The purest mind, the highest vital, the emotive being—the soul influences them, influences them to an extent where one has the impression of entering into contact with it through these parts of the being. So people take these parts for the soul and that is why he says "the inmost soul", that is, the central soul, the real soul. <ref>http://incarnateword.in/cwm/07/3-august-1955#p9</ref>
The surface of the heart centre is the place of the emotional being; from there one goes deep to find the psychic. The more one goes, the more intense becomes the psychic happiness which you describe. <ref>http://incarnateword.in/cwsa/30/the-psychic-being-and-its-role-in-sadhana#p17 </ref>

It is through the emotional being that the psychic most easily expresses, for it stands just behind it in the heart centre.
