Iconography
Vajrasattva is pure white in colour and is sometimes known as the Prince of Purity. His name means "Adamantine Being", or more poetically "Embodying Reality". He is a member of the Vajra family of Akṣobhya which also includes Vajrapāṇi.
He is depicted as a young man in the prime of life, with all the silks and jewels of a wealthy prince. In his right hand he delicately balances a vajra at his heart. In his left had he holds a bell at his waist. The vajra represents Reality, and Compassion; while the bell represents Wisdom.

Vajrasattva is said to have been originated from seed syllable Hum and is generally invoked for removal of obscuration of Kleshavarana and Jneya Avarana. His hundred syllable mantra is very efficacious in purifying our defilements through confession practice. It is said if confession is done with the four opponent powers, then non-virtuous actions or obscurations will be purified. The first opponent power is the force of reliance. This means looking upon the visualized image of Vajrasattva as the embodiment of one’' refuge. The second opponent power is the sincere regret for the non-virtuous action done by oneself. The third opponent power is desisting from evil deeds. The fourth opponent power is to apply power of good deeds; and specially regarding this case, practicing the meditation and recitation of Vajrasattva without parting from Bodhicitta while remaining in the state of emptiness. Vajrasattva is a very popular tutelary deity for Nepalese Vajracharya. He is worshipped very often by Nepalese Buddhists through Guru Mandala ritual.

In some mandalas Vajrasattva represents the Adi Buddha or the Primordial Principle of Buddhahood; in others he changes places with Akṣobhya in the East. In Shingon Buddhism it is Vajrasattva that passes on the initiation of the Dharmakāya Buddha Mahāvairocana to Nāgārjuna, thereby creating the Vajrayāna lineage.

Vajrasattav Purification
Purification of Body
Your disturbing attitudes and negativities in general and particularly those of the body, take the form of black ink. Sickness takes the form of pus and blood and afflictions caused by spirits appear in the form of scorpions, snakes, frogs and crabs. Flushed out by the light and nectar, they all leave your body through the lower openings, like filthy liquid flowing down a drain pipe. Feel completely empty of these problems and negativities; they no longer exist anywhere.
Purification of Speech
Your disturbing attitudes and imprints of negativities of speech take the form of liquid tar. The light and nectar fill your body as water fills a dirty glass: the negativities, like the dirt, rise to the top and flow out through the upper openings of your body: your eyes, ears, mouth, nose, etc. Feel completely empty of these problems; they no longer exist.
Purification of the Mind
Your disturbing attitudes and the imprints of mental negativities appear as darkness at your heart. When struck by the forceful stream of light and nectar, the darkness completely vanishes. It is like turning a light on in a room: the darkness does not go anywhere, it simply ceases to exist. Feel that you are completely empty of all these problems; they are non-existent.
Simultaneous Purification
Do the three above visualizations simultaneously. This sweeps away the subtle obscurations that prevent you from seeing correctly all that exists. Feel completely free of these obscurations.
The Power of the Promise
After reciting the mantra and doing the visualizations, make the following promise to Vajrasattva, specifying a period of time for which you intend to keep it:
"I shall not create these negative actions from now until ."
Vajrasattva is extremely pleased and says, "My spiritual child of the essence, all your negativities, obscurations and degenerated vows have been completely purified."
With delight, Vajrasattva melts into light and dissolves into you. Your body, speech and mind become inseparably one with Vajrasattva holy body, speech and mind. Concentrate on this.

Dedication
Due to this merit may I soon Attain the enlightened state of Vajrasattva, That I may be able to liberate
All sentient beings from their suffering.
May the precious bodhi mind Not yet born arise and grow. May that born have no decline,But increase forever more.
