Contemplative prayer is the exact opposite of what these people are doing. Contemplation is a fruit of mystical theology, and presupposes apprehension of the true nature of the divine, not bogus feelings of "spirit". St. John of the Cross never once "emptied" his mind.
The saints are unanimous in their condemnation of Eastern religious practices. Pope Benedict referred to Indian religious practices as "auto-erotic" and "morally cruel". Here is a news report from 1989 describing a document approved both by our present Pope and John Paul II:
Vatican Warns About Zen, Yoga
VATICAN CITY (AP) - The Vatican Thursday cautioned Roman Catholics that Eastern meditation practices such as Zen and yoga can ``degenerate into a cult of the body'' that debases Christian prayer.
``The love of God, the sole object of Christian contemplation, is a reality which cannot be `mastered' by any method or technique,'' said a document issued by the Congregation for the Doctrine of the Faith.
The document, approved by Pope John Paul II and addressed to bishops, said attempts to combine Christian meditation with Eastern techniques were fraught with danger although they can have positive uses.
The 23-page document, signed by the West German congregation head Cardinal Joseph Ratzinger, was believed the first time the Vatican sought to respond to the pull of Eastern religious practices.
Ratzinger told a news conference that the document was not condemning Eastern meditation practices, but was elaborating on guidelines for proper Christian prayer.
By Eastern methods, the document said, it was referring to practices inspired by Hinduism and Buddhism such as Zen, Transcendental Meditation and yoga, which [may] involve prescribed postures and controlled breathing.
Some Christians, ``caught up in the movement toward openness and exchanges between various religions and cultures, are of the opinion that their prayer has much to gain from these methods,'' the document said.
But, it said, such practices ``can degenerate into a cult of the body and can lead surreptitiously to considering all bodily sensations as spiritual experiences.''
The document defined Christian prayer as a ``personal, intimate and profound dialogue between man and God.''
Such prayer ``flees from impersonal techniques or from concentrating on oneself, which can create a kind of rut, imprisoning the person praying in a spiritual privatism.''
Attempts to combine Christian and non-Christian mediation are ``not free from dangers and errors,'' the document said.
It expressed particular concern over misconceptions about body postures in meditation.
``Some physical exercises automatically produce a feeling of quiet and relaxation, pleasing sensations, perhaps even phenomena of light and of warmth, which resemble spiritual well-being. To take such feelings for the authentic consolations of the Holy Spirit would be a totally erroneous way of conceiving the spiritual life.
``Giving them a symbolic significance typical of the mystical experience,when the moral condition of the person concerned does not correspond to such an experience, would represent a kind of mental schizophrenia which could also
lead to psychic disturbance and, at times, to moral eviations.''
The Congregation for the Doctrine of the Faith is the Vatican's watchdog body for doctrinal orthodoxy. The document did not name any particular individuals, groups or religious movements that have strayed in the use of Eastern meditation practices but the congregation often acts in response to complaints.

The Bible is very clear about the emptying of the mind and Pagans as you pointed out in your post.
I declare and solemnly attest in the Lord that you must no longer live as Pagans do-their minds empty,their understanding darkened.
They are estranged from a life in God because of their life of ignorance and their resistance
