Are there buddhists who criticize Eckhart Tolle as it is not really a buddhist teach? If so, what is their critique?

I've read Eckhart Tolle's book "The Power of Now: A Guide to Spiritual Enlightenment" and if I compare it with Buddhism, I would say Tolle is teaching some form of samatha meditation, that might help someone reach the first or second jhana. Being established in the jhana is being present in the "now" in my opinion.

The experience that Tolle had, which he considers to be enlightenment, is probably just the piti, sukha and samadhi experienced in jhana. I think those who are familiar with Buddhism could read Eckhart Tolle's Enlightenment Story and come to their own conclusions.

Of course as we know, there's a lot more to Buddhism than attaining jhanas. In fact, being addicted to jhanas could be an obstacle to Nirvana.

In his book, he talks about focusing on breath or sensations in the body. These are of course, samatha objects of meditation to induce concentration.

I disagree with those who says that Eckhart's teachings are not Buddhist or Eckhart is not enlightened. It can be true that Eckhart didn't become a Sakadagami immediately as he describes in his books(but it is possible that he became a sakadagami immediately too). But whether he immediately become a Sakadagami or not doesn't matter, it is not a difficult thing to recognise his purity right now. Also Eckhart teaches mindfulness in essence in his teachings, but also teaches things like inner body awareness, or breath awareness to make the beginner meditator's mind calm a little bit. But the core of his teachings is mindfulness. He leads people to give attention to whatever they are doing. Looking, listening, walking, washing the hands, driving, observing the emotions or whatever..This is clearly mindfulness So just looking from this side, Eckhart's teachings are very aligned with the Buddha's teaching.

Ofcourse Eckhart's many descriptions about the nature of the reality fits more with Hinduism. He speak about one consciousness, god etc. So yes from just looking from this side Eckhart's teaching is not aligned with Buddhism.

But we must not forget that Buddhism's main goal is to make people experience the nature of reality themselves. That's why Buddha who was a very intelligent being wanted people to avoid transforming Buddhism to a kind of a worshipping or studying based conceptual belief system.

To sum up, from the experience level Eckhart's teachings are very aligned with Buddha's teachings and from the conceptual level Eckhart's teachings are partially aligned with Buddhism.

As I see it, Buddhism is working through the process of generating a fourth wheel of the dharma — a wheel integrated with the modern, scientific, Christianity-rooted secularism that predominates in the West — and people like Tolle are part of that process. Remember, Buddhism has only been active in the West for a bit more than a century, which is practically nothing in the timeline of a faith.

Of course, traditionalists will always balk at the idea of a new wheel, and will tend to see people like Tolle as interesting curiosities rather than proper teachers. And of course, there's no way to tell if Tolle's influence will withstand the test of time. This is a period of flux, so the status of everything is subject to change without notice. Such is life.

If you call something Buddhism it will be attributed to the Buddha and should be inline with the doctrinal system the Buddha taught. If something is not what the Buddha said then it is wrong to miss attributed something to the Buddha as this is what the Buddha taught. A summary of the majority of Buddha's teaching is encompassed in the Wings of Awakening, 3 Marks of Existence, 4 Noble Truths, Dependent Origination. So if what Eckhart Tolle writes does not have these aspects and if what is found in line with the doctrinal system then you cannot call it Buddhism.

Also some of the core teachings of Christianity and Buddhism are not compatible with each other, so any philosophy influenced by both is neither Christianity nor Buddhism.

There are also Christians who claim he doesn't teach Christianity very well either. Instead, he draws off sources the general public would typically understand. Eckhart Tolle and his teachings are more Taoist than Buddhist. His favorite book to read is the "Tao Te Ching" by Lao tzu. He explains this in his talk called, "Eckhart Tolle - Tao Te Ching and a previous global evolutional era". Although he has very similar teachings to Buddha, he neglects the primary teachings such as the Four Noble Truths, the Three Gems, the Eight Fold Path, and so on...
