Only impersonalists sit and mediate saying nothing and doing nothing, thinking such silence and inactivity is the ultimate goal of spiritual life.

The Spiritual Planets are full of "personal" activities like "always" speaking in loving devotional exhanges of reciprocation with Krishna and all the inhabitants of Vaikuntha and Goloka Vrindavan. 

Only foolish nonsense yogis and Mayavadi impersonalist sit and mediate saying nothing and doing nothing, thinking such silence and inactivity is the ultimate goal of self realization.

Srila Prabhupada - "The Caitanya-caritāmṛta teaches that the spirit soul is immortal and that our activities in the spiritual world are also immortal. 

The Māyāvādīs, who hold the view that the Absolute is impersonal and formless, contend that a realized soul has no need to talk. But the Vaiṣṇavas, devotees of Kṛṣṇa, contend that when one reaches the stage of realization, he really begins to talk. “Previously we only talked of nonsense,” the Vaiṣṇava says. 

“Now let us begin our real talks, talks of Kṛṣṇa.” 

In support of their view that the self-realized remain silent, the Māyāvādīs are fond of using the example of the water pot, maintaining that when a pot is not filled with water it makes a sound, but that when it is filled it makes no sound. 

But are we waterpots? How can we be compared to them? A good analogy utilizes as many similarities between two objects as possible. A waterpot is not an active living force, but we are. Ever-silent meditation may be adequate for a waterpot, but not for us. 

Indeed, when a devotee realizes how much he has to say about Kṛṣṇa, twenty-four hours in a day are not sufficient. It is the fool who is celebrated as long as he does not speak, for when he breaks his silence his lack of knowledge is exposed. 

The Caitanya-caritāmṛta shows that there are many wonderful things to discover by glorifying the Supreme." (Caitanya-caritāmrta Ādi-līiā Vol.I)
