By insisting on certainty and coercing others to secure your own mental and emotional future, you only fix and give more of your reality to personal authority (the ego) and form a solid identity with safety.
To have a sense of security, to have freedom and love at the end, you must have them at the beginning. You must have them now if you want them in the future.
And they are only accessible if you turn inward, if you are accountable for what you feel and think and create. No one else can give them to you. No one can take them away (including God, religion, family, friends, etc.). They are yours anywhere, with anyone, and forever.
