If you feel like a separate and finite individual, you are unlikely to feel equanimity, contentment and happiness. Remember, your feelings are not facts. Just because you feel it, does not make it true. We want connection and when we are unaware of the connection already there, we don't like how it feels.
Get to know yourself, deeply (know you and you know the universe- remember you are of the same essence) and you unite with the universe- you are already one with all, you don’t become one with all just because you just realized you already are. There is nothing to be done, just be aware of it.
Nothing is achieved or reached, you just become aware of it.
Selfless love of others helps you wake up to that reality.
EXERCISE: Do something today that is kind and don’t get caught doing it. Do it without reward. Pay it forward.
Sexual intercourse, done mindfully, with awareness of the divinity in the self and the other, helps with spiritual attainment, heightens ecstatic feelings and helps people wake up to their true nature. It can be an overwhelming process, so there are breathing exercises, physical exercises and purification to prepare people.
EXERCISE: Ask yourself if you are ready for sacred sexuality. Are you comfortable talking about deeper topics or are you superficial (no value judgment, just be honest)? Are you more into pop culture or quantum physics or the metaphysical or spiritual or animals? Can you see the connection to the above?
Are you interesting? Are you sometimes interesting? How can you tell?
Who is interesting in your life and what makes them interesting? Who finds you interesting? Why? Ask them.
What holds you back (fear?) from your full expression? If it is fear, what will you do to face your fear?
Name the fear and come up with an action plan.
Stop reading and do something. If you are simply reading this and not doing anything new, you are guaranteeing no change in your life. Go back and do the exercises and watch how your life starts changing in subtle ways.
