Hi Lalow,
The answer to this one is to follow your heart to find the best way/practice for dealing with your emotions. The Presence Process is an excellent practice for dealing with repressed emotional energy, and emotions that seem to consistently arise and cause us to act out unconscious patterns in our relationships with loved ones, and the world at large.
Alternatively with twice daily Deep Meditation as a permanent, regular habit, it's certain that one will be getting generally calmer and happier. But depending on where you are coming from, this may not always be the sole practice you wish to have for emotions. For many of us, the emotional energy, manifesting as anger, depression, hurt and so on, can be very intense, and cause us to completely lose ourselves, spiraling into unconscious behavioral patterns, or seemingly becoming lost in our thought streams.
For many of us, our spiritual ideals, and the emotional reality of our day to day life, have a pretty large gap. This is certainly how it was for me when I started out on this path. I can't claim to be perfect, but in current experience emotions do now tend to pass through my experience, quickly and cleanly, like clouds in the sky. They don't leave any residue after they pass, and there's minimal or no resistance to them when they arise.
It used to be quite the opposite, and I was deeply emotionally unbalanced suffering from constant emotional reactivity to life. For the practical changes in my life, I can thank regular twice daily meditation, for 4 years, either in the form of AYP, or consciously connected breathing in the style of The Presence Process.
One thing's for certain: if you're regularly doing practices, identification with emotions will be decreasing, you'll find there's a greater, growing awareness, and more of an ability to easily let things go.
My ishta is Truth: The Truth of What I Am - timeless, formless, unbound awareness. So when in the grip of very intense emotions, I sit completely still, I place my hands into prayer mudra, I breathe calmly, I repeat a mental statement to stop myself becoming lost in identification with thought streams about the external event, and I just peacefully stay with what is happening, remembering that I am the awareness within which this is all arising. This is my personal method for ishta redirection. In this way, all emotions are transmuted into a clear-seeing, understanding and letting go of negative emotional reactions to life.
That's just what works best for me, each must find his or her own way.
Love,
Josh
