Of the following techniques, constant sensory amplification and as-needed sensory amplification are applied the most often while performing phase maintenance. However, as opposed to other technical elements of phase exploration, other secondary techniques of maintaining often become mainstream and the most appropriate for certain individuals. Thus, all the techniques should be studied, but the first two should be considered very carefully.

Constant Sensory Amplification

The same sensory amplification described in the chapter on deepening (Chapter 6) also applies to "maintaining". In essence, having achieved the necessary depth of phase, one should not stop to actively agitate his or her perception but should keep on doing this all the while, albeit not as actively as during deepening.

The idea is that during the entire duration of the phase, all action should be focused on experiencing the maximum possible amount of tactile-kinesthetic and visual perceptions. This entails constantly touching and examining everything in minute detail. For example, if passing by a bookcase, touch and examine some of the books in it, including their pages and corners. Tactile observation should be performed on every encountered object.

Palpation may be applied separately as a background sensation. This is done in order not to overload the sense of sight. The hands should be touching something all the time, or better still, rubbing each other.

As-Needed Sensory Amplification

Applying the as-needed sensory amplification technique is no different than constant sensory amplification. It is used only when a foul (a return to a wakeful state) is imminent or when phase vision starts to blur and fade. For example, while traveling in the phase everything may start to blur, signaling a weakening of the phase. At this moment, the practitioner should touch every available object; observe everything in fine detail. As soon as returns to a clear and realistic state, actions may be continued without needing to perform amplification.

Constant Vibration

This technique is used to maintain constant, strong vibrations in the phase. As previously noted, vibrations are generated by straining the brain or tensing the body without using muscles. Maintaining strong vibrations will have a positive effect on the length of the phase.
