The practice is simple. Whatever you're doing, do that with total awareness.
When you deeply love someone from that space that is beyond attachment to certain projections or desires, when you love someone just deeply, totally, completely, without any games that the mind or emotions play, then that love remains eternal in the heavens forever, and that is what pulls you back to remembering that love.
When we sit in meditation, we are closer than usual to the world as it is. By simply bringing body, breath, and mind together in the present moment, we touch Buddha; we touch reality, and we are in the world as it is. Most people’s experience in this state is peaceful and rejuvenating.
You have a unique body and mind, with a particular history and conditioning. No one can offer you a formula for navigating all situations and all states of mind. Only by listening inwardly in a fresh and open way will you discern at any given time what most serves your healing and freedom.
