Vijnana Bhairava Tantra · Dharana 48 · Verse 71
Joy of reunion
When you meet someone you love after a long absence, or when any sudden lift of happiness arrives, do not stay with the person or the occasion. Step into the joy and remain there. The friend, the news, the reunion only set it in motion. The practice is to inhabit the joy before the mind turns it into a story about why you feel this way.

When great joy comes, or when you see a dear one after a long time, meditate on the joy that has arisen. Dissolve into it, and the mind becomes that joy.
