Cohesion

Unity is based upon Intrinsic ( irrespective of externaities of caste, class, age, gender, species and looks)  Principles of Shared beliefs ; the Levels in Unity are dependent upon how far one agrees upon the Shared beliefs; Beliefs are primarily of Honesty : all Relationships are possible due to Honesty alone.

The " Bondings, electromagnetic, chemical and magnetic sense" in Unity  are different from that of strife & associated results ( isolation, within and lack of valuing the beauty of true Friendship).

Referred as Sacred Science or Norms of Affableness , "unity" is fulfilling by intrinsicality.
