Tuning deeper and deeper into subtle sensations is simple and easy enough, as explained earlier. The key component of this process is noticing the very slight shifts of mind that occurs as the attention goes within (into subtlety).
This “noticing” is important because the experience of observing the mind falling into swoon, going into trance creates a deep “getting”…an “Oh wow!” visceral experience of connecting with previously unacknowledged sensations and states of mind.
This initial connecting and “getting” is not necessarily a “fireworks” of awakening kind of experience. There is, however, an acknowledgment of having “touched” a sensation/vibration that feels primal, wild, expansive…like an oceanic reverberation…and ever so subtle at first!
I find it ironic that in all the years of practicing meditation technique, I believe that my mindset of being a monk ultimately got in the way of connecting with the subtle (as well as wild) dance of Kundalini. The overlays of what I could and could not do in terms of lifestyle and meditative techniques fostered a community-mindset and approach that created too small of a “container” that could not hold or support the wild and oftentimes chaotic dance of Her energies when She wished to express through my spine/body.
