Thank you for your great question!
What you are experiencing, I am sure many have. In the example that you gave, note that the problem will arise only if you “value” that particular relationship more than the rest. If someone does not call you, you feel hurt (ego) and in response to that the mind creates many scenarios depending on how you feel about that person. The scenarios are based on the “sanskara” of the day: worry, anger, jealousy, etc.
The issue is that we have expectations about others. When those expectations are not met, then our mind expresses that suffering through “scenarios.” Instant karma.
Therefore, see that ego, that personality; surrounds itself with expectations according to how you view yourself (self respect.) The mind basically expresses ego. It is self suffering. That is what we call a karmic account, but it is based on a sanskara of neediness and expectations.
To change that, in the case of the example; you may want to experiment being “alone,” by yourself and comfortable with that. Watch yourself so you do not create any expectations about anyone, change will happen by itself in due time.
You will notice that in every “ramification of the self,” which in your example are relationships; the main ingredient is to be at ease with you. As long as you feel at peace with just you; neediness to be around people will not be there. In fact, one of the greatest teachings that any spiritual person may want to try, is to live by himself/herself without further contact with others, to be “self-reliant,” in every way. Once you are comfortable here, you will see how life will present you the “opposite” so you can find a balanced life.
The alternative as you know, is a high doses of yoga, so those sanskaras could be submerged;however, it is important to note that a submerged sanskara through yoga, may reappear again, unless it is that deep, volcanic yoga. On the other hand, the solution above (being at ease by yourself) will create a sanskara that will replace the one in neediness, thus; this type of experience is more permanent but it takes time…thus, the solution is to do both at the same time.
Finally, do not assume that your mind knows the answer. Do not assume anything about others. Do not feel “bad” because they do not call you. See that life is training you to go over that hump and your mind will be at ease….
