More of the benefits from using the Wheel:
The way of visualizing the wheel called Om mani padme hum comes in the
tantra entitled The Condensed Secrecy of the Compassionate-Eyed One. It is as
follows: "Light beams from the great Dharma wheel take the delusions, sufferings
[Skt. dukkha], imprints (or predispositions), and seeds of all sentient
beings in the six realms and cause these to be collected and absorbed into the
six -syllable wheel. All the disturbing thoughts, karmas, seeds, and imprints are
burnt, destroyed, and purified. If one does this practice, one is liberated from
the causes, conditions, and results of samsara-from all disturbing thoughts,
karma, and obscurations. This is the wheel cutting the root of samsara. Keep
extremely secret and cherish this practice.
"Through light beams emanating from the mantras of the precious wheel
and striking migratory beings, they spontaneously develop the four immeasurable
thoughts-loving-kindness, compassion, joy, and equanimity. They complete
the practice of the six perfections-giving, morality, patience, perseverance,
concentration, and wisdom."
