This question reminded me of this Bible passage :
“34 “Do not think that I came to [ac]bring peace on the earth; I did not come to bring peace, but a sword. 35 For I came to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law; 36 and a man’s enemies will be the members of his household.
37 “He who loves father or mother more than Me is not worthy of Me; and he who loves son or daughter more than Me is not worthy of Me. 38 And he who does not take his cross and follow after Me is not worthy of Me. 39 He who has found his [ad]life will lose it, and he who has lost his [ae]life for My sake will find it.”
Matthew 10: 34-39
The battle field is the terrain of our day to day existence. If we choose to take up a spiritual path, we inevitably meet with resistance, because eventually you will likely find yourself outside the norm–even with friends and loved ones. If we choose to pursue our higher Self, we must exercise detachment in our earthly relations, and choose the right actions to achieve Union with Self (and God if you’re religious). In doing so, we shed our old understanding and way of living and take up a new one.
