Renunciation !

http://www.accesstoinsight.org/lib/authors/prince/bl036.html

Renounciate from any concept and material that is solid, subjective, non changing, perfect, and self clining.
There is no such thing as true love in the worldly samsara.
Your parents will betray you, and so does your lover ... And your best friends....
First step into tantra practice is renounciation.
Second step is compassion.
