Introduction.
How to Love when one has to be free from illusory delusions, from attachments and clinging?
I do not know, but I think & try as best as i can. I aspire to understand the Enlightened Love, and to practice and prepare to practice the Enlightened, the Unconditional Love.
My current understanding is described in this article, I hope that my understanding will deepen and improve as time passes.
Definitions.
Beings differ from Phenomena in that beings have mind (having mind means that beings are mind and have bodies), while phenomena do not have mind.
Understanding the illusory nature of beings and phenomena means understanding that they/these will keep changing forms. This means that beings and phenomena will arise (be born), change and pass away (die). This process will keep repeating and continuing until one reaches Enlightenment, or so I think.
Time between death and rebirth is called: 'Bardo'.
Word: 'Bardo' literally means: 'between two', but - in buddhism at least - it often means one's state between death and rebirth, in short. (there are many bardo states, including: 'bardo of dying', 'bardo of meditation', 'bardo of dream', and more).
Attachment and clinging can refer to being enslaved/obsessed with someone's/something's current state, current form.
Emptiness of all beings and phenomena meanst that everything is nonpermanent, that everything changes and has 'illusory nature'.
How to be free of ego-attachment?
I think that one should understand the passing nature of one's ego, understand that one changes constantly. One should not cling to one's 'current form'. I think - but i have serious doubts on that still, so check by Yourself please - that one's body is part of the mind, that one's ego affects how one experiences body as existing in the current state, current form.
How to Love without clinging?
I think one should practice the Unconditional Love, the Enlightened Love that 'Has the Taste of Freedom'.
I think one should fight for Love instead of forcing a partner to be together with the 'other half' against his/her will.
I think that one should accept if/when a partner wishes to leave - either for a short while or for longer.
I think one should accept that Loved one will age and die, and accept that current forms will change, including the acceptance that partner's beauty will pass away with age.
One can still strive to be lover or a friend again, either in this or in next lives, I think.
I think that one should see a partner as mature person, as one who is liberated from ego, and should aspire for self-liberation as well.
