II श्रीराम जय राम जय जय राम II

गुरू को चेला बीष दे, जो गांठी होय दाम I
पूत पिता को मारसी, ये माया का काम II

All human relationships are conditional. Every relationship comes with expectations. In any relationship whether it is a marital relationship, sibling relationship, Parent and child relationship or any relationship, there are always some or other expectations.
We may try to fool ourselves that it is good not to expect anything but from the inside i.e., subconscious mind, we expect something or the other. We can have unconditional love in our hearts and minds, but relationships are inherently conditional because they live in the world. We engage with each other on several levels, psycho-emotional, spiritual, intellectual, personal, professional, social and more. So at any time you are interacting with someone you could be making exchanges simultaneously on more than one plain without even realizing it. Since expectations are tied to feelings and experiences as well as ideas, rewards can be pretty high when expectations are fulfilled and disappointment pretty intense when expectations are not met, for expectations is the root of all heartache.

"Kabir says, unconditional love in the worldly perspective is a romantic illusion. It has no boundaries. But the real world is conditional. Your love for your partner is not without conditions. Neither is your parents' love, platonic love with friends, or other family members, or their love for you.
Illustrating with meaningful analogy he says, the greedy disciple  murders his Guru by poisoning him thus tainting the sacred Guru - Disciple relationship, a majestic, and a loftiest relationship based on the Guru's unconditional love for the disciple.
In another analogy he says, a son desecrates the sanctity of parent-child relationship, killing his father. 
Summing up Kabir says,  the name-and-form, is what we call as Maya, the illusion. The feelings of "otherness" is the ego-mind in action. We want to force our ego-vision on others to follow so our false ego-sense can get satisfaction. But this false ego-sense can never be satisfied. In fact, more we gratify it more it flares. It is like pouring more fuel over an already burning fire. The ego feeds on attention. Without attention, the ego will starve. But it does not want to starve. Therefore, it wants attention giving rise to the feeling of "me, mine" and "others". When there is no "me, mine" and "otherness", there is no ego. Then there is only the selflessness and true love."
