From the perspective of a Vajrayana practitioner (or Dzogchen):

Those pure lands are not anywhere else –
they abide in your own heart within its center and four directions.
They now emerge from out of your heart and appear to you!
Those images do not come from anywhere else!

– From Liberation Upon Hearing in the Bardo by Karma Lingpa

Notes:

Commonly known in the West as The Tibetan Book of the Dead, the Bardo Thödröl (Liberation Through Hearing During the Intermediate State) is a text from a larger corpus of teachings, the Profound Dharma of Self-Liberation through the Intention of the Peaceful and Wrathful Ones, revealed by Karma Lingpa (1326-1386). It is the best-known work of Nyingma literature.

The Tibetan text describes – and is intended to guide one through – the experiences that the consciousness has after death, in the bardo, the interval between death and the next rebirth. (The text also includes chapters on the signs of death and rituals to undertake when death is closing in or has taken place.)
