Although the reader said the word "hold" I believe he was referring to Kumbhaka - a pause in the breath. This is a common pranayama technique used in yoga practice to control the mind.
Feeling dizzy during meditation especially with progressively ,increasing concentration and decreasing flow of thought is natural. Dizziness is caused by the accummulaion of energy called prana or consciousnessi n the head and spinal cord. In very advanced stages of meditation dizziness is persistent at all waking periods and usually becomes quite worrysome. to avoid this condition you should start with a proper meditation .methodology involving body exercises

i'm surprised there's no mention of Prana here. i have this same issue and it generally takes place during or after a class where i've been breathing rhythmically and deeply for a long time. it also happens when there's a healthy, free flow of Prana through the body. i think it's healthy and restorative and a sign of an open practice. you have to be careful not to push so far you pass out though! when you find yourself light headed quickly bend forward and put your hands on your knees for support. then keep on breathing!
