Yamantaka/gnosis?

I have a question for my readers: Does this description of 'the enlightening activity of wisdom' sound like gnosis to you?

How does Yamāntaka terminate death?

Directly from Wikipedia.org-- "This question depends upon the meaning ascribed to the term death – but one way in which this ability can be identified is through the enlightening activity of wisdom. The wisdom mind is able to perceive that death has no intrinsic, concrete existence: our understanding of death emerges solely from the conventions of the world. Also, when we achieve the same realisation of Yamantaka - who is a Buddha - then we have transcended death.

There are three types of death spoken of in the Yamāntaka Tantra : Outer death is the regular end of life, which is embodied by Yama, Lord of Death, who resides in the south, seven stories under the earth. The inner death is ignorance of the true nature of non-dual reality. Instinctive habitual grasping and aversion to objectively "real" objects and subjects arises from this ignorance. The secret death is dualistic appearance on the subtlest level of clear light mind and illusory body. With the practice of Yamāntaka one overcomes those types of death and gains immortality as a Buddha."
