Hello
LiberatedLotus.
Your question that is posed as the thread's title would be helped by some more clarification. What do you mean by "immortality"? The inner spirit is immortal, thus in that sense one does not actually achieve it, but may awaken to it and align with it. There is refinement in liberation, not just a point a person may reach in which he or she is "liberated" without room for further liberation and growth.
You also asked if liberation can be reached through a holistic approach. Liberation can
only be reached through a holistic approach, although in terms of human experience liberation is more accurately seen as a journey of expanded consciousness and integration, rather than just an end goal that may be reached.
"Holistic" in its highest meaning being through an attitude and awareness of whole-mindedness, which is a holy attitude, a holy approach.
Holy,
holistic and
whole in this instance all referring to our True Divine Nature.
Meditation (as alignment with one's inner being) is indeed fundamental to this process, which indeed affects the
chakras, and those other tools you mentioned may also be of great benefit, as long as there is a pure intention in using them.
You mentioned "combat." Combating anything is not a high state or action, and it perpetuates conflict and frustration in one's life. There is no need on the part of the inner spirit to combat anything; only the lower self, so to speak, the lower ego, is that which is interested in fighting and defending itself from attack.
This is why in the state of meditation (spiritual alignment) there can be no resistance or defending anything. The moment one entertains a defensive thought and personally identifies with it, one veers off-course from the meditative awareness.
Sending love, embodying love, is the best form of "combating darkness," so to speak, except that it is not really fighting it off, it is really allowing oneself to raise one's own vibrational frequency to such a level that one's own lower-level energies are burned off and transformed. In this way, other low-level energies or entities cannot attach themselves to such a high-vibrating person. The
Violet Flame meditations are very good for assisting with this.
As a quick mention, any individual that engages in sacrifice is actually a slave to low-level magic, no matter if such a person has done great damage. Great damage doesn't equal great power in a spiritual or magickal sense. Any form of influence or magick that is parasitic in nature is low-level, it IS
novice from the perspective and understanding of a high-level adept, as such low-level magick
always creates great negative karma for the one who practices it. Such individuals are not aligned with the Higher Self when engaging in fear-based, manipulative magick that feeds upon the energies of others (i.e., such things as blood sacrifice, slavery, etc.).
I suggest the safe usage of candle magick, incense and prayers of light, envisioning yourself as enfolded in a great aura of White Light, as highly beneficial, as long as such activities are not done in an attitude of resisting or fighting off darkness, and I do believe that you are one who respects both polarities of "light" and "dark" to a high degree, which is very spiritually mature of you.
I wish you the best.
Namaste
