Truth- Realization or Self-Realization or God Realization 
Truth realization or Self-Realization or God Realization is a very
deep topic.  One might ask what truth
-realization is? Truth realization is realization of the knowledge of the true self to get unity in
diversity.  Identifying self  as formless soul leads  to non-dual Self-Awareness or Brahmic -Awareness or Atmic-Awerness. 
 Self- knowledge  or Brahma Gnana or Atma Gnana is
not theoretical knowledge based on the physical self [ego] but the knowledge of
the ultimate truth on which the physical existence [illusion] is dependent.
Self-knowledge is the True Knowledge.

What is Self -Knowledge or Brahma Gnana or Atma Gnana? 
Self - Knowledge or Brahma Gnana or Atma Gnana  is Knowledge of the innermost  self. Self-knowledge
or Brahma Gnana or Atma Gnana is required to overcome the duality. Self-knowledge or Brahma Gnana or Atma Gnana comes through deeper self-search.  Self- Knowledge or Brahma Gnana or Atma Gnana  unfolds the mystery of the mind or universe in,which we exist. 
Gnanis have this Self - Knowledge or Brahma Gnana or Atma Gnana . People think there are many
sources to acquire the Self-Knowledge or Brahma Gnana or Atma Gnana , but fail to acquire it from many
sources. Those who are lucky will follow the path of wisdom.  It is impossible to acquire
Self-Knowledge or Brahma Gnana or Atma Gnana  from any other source, other then the path of Wisdom. 
Only those serious seekers of truth do not leave a stone
unturned in their quest of ultimate truth, will realize the fact that, only
through soul-centric  reasoning it is
possible to acquire non-dual wisdom.
There is no other Reality other then realizing the fact that,
the soul or consciousness  is the true self. Everything in the experience of diversity is created
out of the soul and sustained by the soul and finally everything dissolves as
soul.  
Seeker has to remember Self-Knowledge or Brahma Gnana or Atma Gnana is the Gateway to get
unity in diversity. Self-knowledge or Brahma Gnana or Atma Gnana is the key to know the illusion and reality
are one in essence.
