Absence of light is a total darkness,
Absence of companion is loneliness
While absence of knowledge about yourself is ...?
Knowing about yourself isn't knowing about your likes and dislikes or hobbies and love interest.,
The very existence of you, alone is big question ..
Answerable by YES or NO .. Maybe ..
Intentions, motives, perceptions, goals, does those count?
Knowing yourself is knowing the purpose of your existence ..
Sight is clear, without obstruction ..
Meditate .. Think only of you, and things that could benefit you, and creatures that surrounds today and someday ..
