This is a rare find - old sets are difficult to come by that are in excellent condition both in stature & sound. The Ganta Bell is the ultimate universal symbol of Transcendent Wisdom.
The Dorje/Vajra, (Vajra in Sanskrit/Dorje in Tibetan), is the representation of purity, the transcendental state of "emptiness" and the highest form of Love - Compassion. The sound of the Ganta (Bell) is regarded as auspicious in Tibet and used to drive away negative attachments. It represents the receptive Feminine energy and is used in the left hand as it draws in Wisdom. The Dorje represents the Masculine energy and is used in the right hand to project and transmit Compassion outwards.
The Ganta and the Dorje are always used together. In practice, the ringing of the Ganta calls beings to practice, and warns off malign influences and is also a musical offering. This is the the union that reveals enlightenment.
