“That which is known as "meditation" is the act of sustaining an object of meditation and specific subjective aspects by repeatedly focusing your mind upon a virtuous object of meditation. The purpose of this is as follows. From beginningless time you have been under the control of your mind; your mind has not been under your control. Furthermore, your mind tended to be obscured by the afflictions and so forth. Thus meditation aims to bring this mind, which gives rise to all faults and flaws, under control and then it aims to make it servicable. Servicability means that you can direct your mind as you wish toward a virtuous object of meditation.”

[Swami Tapasyananda, Swami Nikhilananda, Sri Sarada Devi, the Holy Mother; Life and Conversations, 351-352]

The meditator is the observer, the senser, the thinker, the experiencer, and when there is the experiencer, the thinker, then he is concerned with reaching out, gaining, achieving, experiencing. And that thing which is timeless cannot be experienced. There is no experience at all. There is only that which is not nameable. ...You know, in all this there are various powers like clairvoyance, reading somebody’s thought — which is the most disgusting thing to do: it is like reading letters that are private. There are various powers. You know what I am talking about, don’t you? You call them siddhis, don’t you? Do you know that all these things are like candles in the sun? When there is no sun there is darkness, and then the candle and the light of the candle become very important. But when there is the sun, the light, the beauty, the clarity, then all these powers, these siddhis — developing various centres, chakras, kundalini, you know all that business — are like candlelight; they have no value at all. And when you have that light, you don’t want anything else.

"What is Meditation?" (2006)
Context: Mind without agitation is meditation. Mind in the present moment is meditation. Mind that has no hesitation, no anticipation is meditation. Mind that has come back home, to the source, is meditation. Mind that becomes ‘‘no mind’’ is meditation.
