Something tangible to be done. Not that this so-called meditation. Meditation will automatically be there. If you do, if you sacrifice your life for serving Krsna, you will always remember Krsna. You will always remember Krsna. Just like you are taking so much trouble, going place to place to give one book to somebody. Why? Because you love Krsna, and you are thinking if this gentleman takes one book, never mind, small or big, he’ll read at least one page about Krsna. So you are thinking of Krsna. That is meditation. Not that simply sit down at a place. The real meditation is how  to think of Krsna. That is real meditation. I am thinking of some light or some sky, like that — they are not meditation; they have manufactured now. Because they have no connection with the Supreme Personality of Godhead, so they think these are the meditation — some light, some sky, some vacant. No. Some tangible thing, we should be always. That tangible thing is Krsna: Krsna’s form, Krsna’s pastimes, Krsna’s activities, Krsna’s desire, how to fulfill it, that is wanted. That is Krsna consciousness.
