How do we hold on to good feelings during meditation?.

Question:

“Dear Deepak, For a number of years I have tried to follow your suggestion of simple meditation focusing on breathing for 20 minutes in the morning and 20 minutes late in the day. 

I don’t always reach a totally calm level or reach a full 20 minutes but I more or less receive the benefits I am looking for. 

One thing that happens repeatedly is as my mind starts to slow down, I feel a quick “surge” or “rush” through my head & neck area almost like a low-level electrical “jolt” that lasts only for a second. 

I notice it when I arrive in “the gap” for a split second and this “surge” is strong enough that I physically jerk a bit the moment I experience it and this in turn sort of interrupts/changes my focus. 

It’s to the point that I am very familiar with this momentary “surge/jolt” experience and I can almost summon it at will even when I am not meditating. 

The interesting thing is I can only hold it for a second or so and it is always during a short “gap” moment. 

Can you explain or comment on what you think might be happening and is there a technique to prolong or hold this “surge” experience? 

Although it only lasts a moment it is a deep/profound experience I would like to further cultivate and see where it goes. 

I am sure you know precisely what I am describing so any suggestions/advice is greatly appreciated. 

Thanks so much for your work. It has helped me immensely.”
