What do we need? We need a pure mind. With a pure mind we can enjoy everything as pure, there is no samsara, impure suffering life. Samsara exists only within an impure mind. Happiness is the appearance to a pure mind and suffering is the mere appearance to an impure mind.
An empowerment allows us to make a connection with Enlightened beings and receive the blessings of their pure body, speech and mind. Through receiving the powerful blessings of Vajrasattva and engaging in this practice we will come to gradually experience the reality of our own pure mind.
