Samsara, our conditioned existence in the perpetual cycle of habitual tendencies and nirvana; genuine freedom from such an existence are nothing but different manifestations of a basic continuum. So this continuity of consciousness is always present. This is the meaning of tantra.
According to Buddhist practice, there are three stages or steps. The initial stage is to reduce attachment towards life. The second stage is the elimination of desire and attachment to this samsara. Then in the third stage, self-cherishing is eliminated."
