If you're interested in meditation in this lifetime, and buddhism, you've probably practiced before. We are drawn back again, in each lifetime, to pick up where we left off. You may have a great deal of past life knowledge and power stored inside you and the way you access it is by practiciing meditation.

 It is best to meditate twice a day in the morning and the evening.  If you meditate in the morning, you will energize your body, mind and spirit, clarify your purpose and just become happy.  Then you're happy all day, successful all day.  Then at night, meditate again and enter into the world of light, fill yourself with light and you'll have a perfect night. 

The central theme or theory of yoga/buddhism is that happiness is not something that you really gain in the world. In life we see most people trying to become happy through their careers, their relationships, their school or athletics, hobbies, pastimes, or whatever. Certainly a certain amount of happiness can be gained through those things.  But also, it would appear, judging from most people's experiences, that more unhappiness is gained than happiness.  I mean, there aren't many happy people around.  You don't see many smiles in the world.  

 So happiness does not necessarily come from experience nor knowledge.  Yet there is happiness in knowledge.   Happiness in knowledge, for sure, can come from meditation. There are worlds of happiness and knowledge outside of this dimension.  Meditation is a way of getting to them.  If you sit down in the morning and meditate, you will experience happiness, knowledge, you'll gain power.  Then all day long you'll be happy.  No matter what happens, you'll be happy. If you have a happy day, then great, enjoy it! But if you don't, you won't lose your happiness. You've stored it up in your morning meditation.  And then you'll gain more in the evening.

Meditation puts an end to the dependency, for happiness, on physical things -- on people.  If you love someone and they die, your life can be ruined, you can be miserable. But if you meditate, that's so, of course you'll experience sadness. That's natural. But because you meditate and you see that there's no death and because you experience radiant happiness in your meditation and in the practice, you'll be happy no matter what happens.
