Any verbal knowledge or words without any direct/ imaginary visuals or music will not go into the sub conscious mind

A word with a direct or imaginary image or visual stays in the subconscious mind for a long time. Words with melodies are also getting absorbed in the same way. This strategy is also applicable for the acquisition of all other learning subjects.
