Krishna deciphered existence and said that it is the combination of 𝙥𝙧𝙖𝙠𝙧𝙞𝙩𝙞 (nature) and 𝗽𝘂𝗿𝘂𝘀𝗵 (spirit) both of which are beginningless. 𝙂𝙪𝙣𝙖𝙨 (qualities) and 𝙫𝙞𝙠𝙖𝙧 (evolution or change) are born of 𝙥𝙧𝙖𝙠𝙧𝙞𝙩𝙞  (13.20). While 𝙥𝙧𝙖𝙠𝙧𝙞𝙩𝙞  is also responsible for cause and effect, purush experiences them as polarities of 𝙨𝙪𝙠𝙝 (pleasure) and 𝙙𝙪𝙠𝙝 (pain) (13.21). Krishna further clarified that HE is beyond perishable 𝙥𝙧𝙖𝙠𝙧𝙞𝙩𝙞 and even higher than imperishable 𝗽𝘂𝗿𝘂𝘀𝗵 , thus proclaimed as 𝙋𝙪𝙧𝙪𝙨𝙝𝙤𝙩𝙩𝙖𝙢𝙖 (Supreme Being) (15.18). This recapitulation will help us understand the following verses.

Krishna says, "Those possessing a demonic nature do not know action from inaction. They neither possess purity nor proper conduct nor truthfulness (16.7). They say that the world is without absolute truth, without any foundation, without a Lord. It is nothing but born of mutual union (of male and female) caused by lustful desire"(16.8). Essentially, this is living a life at the level of 𝙥𝙧𝙖𝙠𝙧𝙞𝙩𝙞  where cause and effect dominate; where logic defines everything that we experience.

The next question arises as to what the behaviour of someone who is at the level of perishable 𝙥𝙧𝙖𝙠𝙧𝙞𝙩𝙞 would be. In this context, Krishna says, "Holding on to such views, these misdirected souls, with small intellect and cruel actions, arise as enemies of the world threatening its destruction (16.9). Harboring insatiable desire, full of hypocrisy, pride and arrogance, possessing evil ideas through delusion, they work with impure resolve (16.10).

In a nutshell, demonic natured people live at the level of cause and effect of 𝙥𝙧𝙖𝙠𝙧𝙞𝙩𝙞 without realising the 𝙋𝙪𝙧𝙪𝙨𝙝𝙤𝙩𝙩𝙖𝙢𝙖 behind this. While the metaphor of male-female union for creation is logical and many actions and thoughts we see around us fall in this logical category, a mother's pure joy of unconditional love is beyond logic. The journey is moving from bondage of logic to liberation of unconditional love.
