If you learn how to practice love, compassion, joy, and equanimity, you will know how to heal the illness, anger, sorrow, insecurity, sadness, hatred, loneliness and unhealthy attachments.
Whoever practices the Four Immeasurable Minds together with the Seven Factors of Awakening, the Four Noble Truths, and the Noble Eightfold Path will arrive at deep enlightenment.
The first aspect of true love in Buddhism is friendship.
The second aspect of true love is compassion.
The third aspect of true love is joy. True love always brings joy to us and the ones we love.
The fourth element of true love is equanimity: nonattachment, nondiscrimination, even mindedness, letting go. If your love has attachment, discrimination, prejudice, or clinging it is not true love. This is the wisdom of equality.
