(1) Jnana, in Sanskrit means "the most desirable acquisition in both Hindu and Buddhist philosophy. Without it there is only ignorance, ajnana, the cause of suffering and evil.

Interpretation 3

The index finger designates and identifies ourselves. The thumb is the strongest finger and is the only one opposite to the others. It represents the universe as a partner to our self. In this way, linking the index finger and the thumb, we signify the union of our self with the universe, of the microcosm and the macrocosm. The other fingers are held under control and understood as:

• The middle finger represents selfishness and vanity
• The fourth finger represents the attachment to passions
• The fifth finger represents Mayà, the power of illusion.
