MEMORY (स्मृति)

Do you want to sharpen your memory? 

"Remember these 8 points and follow it by heart." 

Acharya Charak says, there are   eight factors to bring about a good memory:

1.  Knowledge of cause of a thing (निमित्त ) 
2.  Knowledge of form of a thing (रुपग्रहणात) 
3.  Knowledge of similarity( सादृश्यात्) 
4.  Knowledge of contrast (विपर्यात्)
5.  Concentration of mind(सत्वानुबंधात्) 
6.  Practice(अभ्यासात्) 
7.  Knowledge of Metaphysical knowledge (ज्ञानयोगात्) 
8.  Seeing, listening and experiencing to something again and again (पुनःश्रुतात, दृष्टश्रुतानुभूतानां)
