I recommend computer science to people who practice meditation. The mental structures that are used in computer science are very similar exercises done in Buddhist monasteries.

It is not advisable for persons who are in the early stages of meditation to mediate on the two lower chakras. You will unleash powers and forces that will throw you into very powerful altered state of consciousness that might not be pleasant at all.

You did something noble. This will cause a release of energy. It causes a vibratory shift. It means you are moving into a different plateau of consciousness.

You cannot compel someone to love. Love is like the wind. It comes when it does, it stops when it does, it changes direction when it does. Who are you and I to criticize the wind?

I'm not suggesting that everyone should meditate, far from it. Meditation is for very few individuals. I'm speaking of something that is a powerful experience.

Look at the big picture of the wheel of life. Above it, there is a Buddha. He is pointing, not towards the wheel, but away from it. He is indicating that there is something else - nirvana.

Nirvikalpa samadhi is another matter. In order to enter into nirvikalpa samadhi, you must have a great deal of humility.
