Epsilon is the most profound of audio entrainment techniques I have used . I have been using these techniques for many years and I salute you and your team for such enlightening work.  ~ Lynette

Epsilon Meditation

There is deep, and then there is deep.

Though the brainwave patterns on the Primary Meditation Tracks go as low as 0.3 Hz—which is truly deep enough for advanced spiritual growth—some of us really would like to go as deep as possible in meditation. For those of you who share this aspiration, Epsilon  takes you there. The frequencies on these tracks range from 0.1 Hz to 0.001 Hz.

I’ve had some of the deepest ever with Epsilon including full blown mystical experiences. Very deep, and yet I stay perfectly awake 90% of the time, even to Epsilon.  ~ Jamie Basil

Listen to the 5-Minute Sample Now

Use of headphones is required to experience this demo properly.
To fully experience the potential of this program, please get comfortable, close your eyes and relax for the next 5 minutes. Allow the ocean waves to immerse you in a deep sense of relaxation and peace.

Don’t be fooled – this is not just beautiful ocean waves – it is the design and technology infused in the soundtrack that evokes the deep relaxation response.

Why would you want to take your meditation practice to the very limits?

Maybe just because you can. But also, there is evidence to suggest that these ultra-low frequency brainwave patterns can act as carriers for some of the ultra-fast frequencies found in highly advanced meditators and associated with extraordinary experiences and insights.

The Epsilon  tracks are thus one of the most experimental and cutting-edge aspects of the overall Profound Meditation Program.  The feedback from early adopters has been phenomenal, and we invite you to join us in the adventure.

Use these tracks to supplement, extend, deepen, and add even greater dynamic variability to your Primary Meditation.

Consciousness researcher Dr. Jeffrey Thompson altered conventional EEG equipment to study the extraordinary states of consciousness of seasoned meditators and yogis. He later decided to call one of these uncommon states of consciousness he discovered Epsilon, a brainwave pattern even slower than Delta.

Dr. Thompson measured the range of this pattern to be from below 0.5 Hz (or cycles per second) to as low as one quarter cycle every ten seconds. He also discovered properties of this pattern that led him to believe it to be a carrier wave for the ultra-fast brainwave patterns he observed in other expert meditators, patterns as fast as 200 Hz or more.

How to Use

Download the iAwake App

First, download the FREE iAwake App, login with your email and all your tracks will be right there. You can stream them, but we’d advise downloading them (from within the app) to ensure an interruption-free experience, and to be able to listen offline.


Important Note on the Optimal Use of Epsilon

The Epsilon  sessions do not feature a ramping descent that begins at the Beta pattern (which will most often be the predominant pattern before starting a meditation session) and slowly descends to the Delta pattern.

Optimal entrainment, therefore, will occur if you first listen to Track 1 (Descent from Beta to 1 Hz Delta in the first 16.5 min, followed by 3.5 min of 1 Hz entrainment) of the Primary Meditation Tracks of Profound Meditation Program 3.0  before listening to Track 1 of Epsilon.

An example meditation session would be as follows:

Primary Meditation Tracks (from any one of the three Tiers) – Track 1 – 20 minutes
Epsilon – Track 1 – 20 minutes
Epsilon – Track 2 – 20 minutes
Epsilon – Track 3 – 20 minutes

Total of 1 hour and 20 minutes meditation session

Listening to Epsilon Track 1 (or any of the Epsilon tracks, for that matter) without first listening to Primary Meditation Track 1 will still result in entrainment. The resulting degree of entrainment, however, will usually not be as great as it is when first listening to Primary Meditation Track 1.

To experience the greatest degree of entrainment with Track 2 of Epsilon, it is advised to first listen to Track 1 of Epsilon.

Likewise, with Epsilon  Track 3, optimal entrainment will occur when it is preceded by Epsilon  Track 2.

Because Epsilon  Tracks 2 and 3 are uncommonly deep, it may take a few minutes after having begun before you notice your brain “locking in” to the entrainment signals.

The more often you use the Epsilon  tracks, the more deeply you will entrain to their signals as repeated use trains the brain to respond more sensitively to the entrainment stimulus.

The Epsilon  tracks add yet another element of variety to Profound Meditation Program 3.0, allowing for the greatest degree of variability and precision stimulation.

Epsilon tracks which I use only at night when I know I am going to bed right after, they have a soporific effect on me. And I deeply enjoy it.  ~ Antoine Rousseau
