Simultaneous peering and palpation provide the maximum possible deepening effect in the phase. This method of sensory amplification engages the two most important perceptions, thus the effect is twice greater than when the two actions are separately performed. If vision is present in the phase, simultaneous peering and palpation is an absolute necessity because it facilitates good phase depth in the quickest and simplest manner. The combination of palpation and peering must not only be performed simultaneously, but also upon the same objects. For example, a practitioner may look at his hands and simultaneously rub them against each other; or while looking at a coffee mug, all of its parts may be observed and touched at the same time. It is necessary to maintain dynamism of action, remembering that feelings should be experienced not half-heartedly, and remembering that full concentration on sensory amplification is an excellent means to a deep, quality phase. Sensory amplification comes intuitively when you remember a simple rule: if some sensations are lacking or if one of the five senses is dull and vague, then that sense needs to be heightened as much as possible using the phase space. The previously lacking sensation will become intense and highly-charged. In case of dim vision, for example, one ought to scrutinize something more and more fixedly from a close distance. When experiencing weak bodily perception, palpate your body and move it in as many different ways as you can. SECONDARY DEEPENING TECHNIQUES Diving Headfirst Diving headfirst is used if sensory amplification techniques do not work, or when the practitioner in the phase is located in an undefined space where there is nothing to touch or look at. This technique works thanks to the unusual vestibular sensations that it causes, which help to enhance perception. This technique is performed with the eyes shut if vision is available and the practitioner literally dives headfirst
