7. Nīkashūm Simshūmbīsī» Meditation
Based on the July Mamsani
First focus on your breath—nine counts in, holding one beat, and nine counts out, holding one beat. Once it is regulated and relaxed move to the next step. §
Spend a few minutes watching your thoughts, how frequent or infrequent they are, what topics they are centered above. Then observe your emotional nature, what you are feeling and toward whom, if you are reacting over any recent events. Withdraw your energy from these two areas into the actinic energy within the spine. Do this on the out-breath. Visualize a clear tube within the center of your spine being filled with yellow light coming from the top of our head. See the pure life force, yellow in color, flowing through the spine and out into the nerve system.§

Quote from Gurudeva§
When we begin a religious pilgrimage or retreat into sadhana and we want awareness to dive deep within, we have to withdraw the energy of the vibrating ida and the vibrating pingala current into sushumna. This is quite a chore, because these currents have had energy flowing in them for a number of years. So, to rechannel that energy is to rechannel the entire circumference of awareness into the sushumna current. This takes a lot of practice.§

Twelve Shum Meditations Shum-Tyeif Mamsani for the Month of July§
The first portrait in this mamsanī is a practice of the inner feel within the fourth dimension when awareness is in the area of the mind named kalībasa. The breath is regulated from the inside out—nine counts in, holding one beat, and nine counts out, holding one beat. When you are aware within this particular area of the mind from the inside out, your breath will automatically be regulated. But to get into this area of the mind, called kalībasa, you can also regulate your breath from the outside in. So, it can be approached in either one of two ways.§
The next portrait, vūmtyēūdī, is the vibration of the intellectual area of the mind. When we are in the area of the mind that is always thinking, aware of thought patterns, reason patterns and memory patterns, this is called vūmtyēūdī. It is a fourth-dimensional area. Karehāna is also within the fourth dimension. It names the “feel” of the physical body, the magnetic forces of the physical body, the instinctive nature of the physical body and the emotional unit.§
Nīkashūm is the wonderful practice of withdrawing the energies of awareness from vūmtyēūdī and karehāna into their source, Nīkashūm. As we breathe in, kalībasa, we pull the energies back out of the physical body, out of the emotional, out of the intellectual, into the spine. Nīkashūm, the withdrawal of energies, is a third-dimensional picture. And when you are in that area of the third dimension, nīkashūm is what automatically happens.§
