Over a period of time you will come across people who will give you lots of varieties of advice.\n1. first remember that meditation is solely for control over the senses.To the person who practices, his main aim should be to control the wavering of the  mind. Dawn and dusk are excellent periods for such practices.\n2. Meditation doen't mean merely concentrating for a few hours. You HAVE TO practice the following:\n                 SEE NO EVIL\n                 HEAR NO EVIL\n                 SPEAK NO EVIL\n                 THINK NO EVIL\nThe first and last are of paramount importance.Lapses in the above result in the kundalini slipping back to it's original place. But if you suceed, over a period of time, the kundalini shakti comes up to it's zenith and your mental and intellectual power are extremely enhanced. \n         So good luck. You are on the right path and remember it needs lots of practice and patience.
