The difference between the Māyāvāda philosophy and Vaiṣṇava philosophy, that the Māyāvāda philosophy, they want to stop activities. They think stopping of all activities is perfection, śūnyam, śūnyavādi. Nirviśeṣa-śūnyavādi. Simply stop material. But what is the positive engagement? That they do not know. That is the difference. Positive engagement means serving Kṛṣṇa. That positive engagement means, engagement means, acting means, the employment of the senses.
So when we employ our senses in the positive activities, that is liberation. That is liberation. Just like a diseased man and a healthy man, what is the difference? The difference is that a healthy man is engaged in healthy activities, and the diseased man is engaged in diseased activities. The diseased man is also lying down, and the healthy man is also lying down. There is vast of difference. The diseased man is also eating, and the healthy man is eating. There is vast difference. So these activities, devotional activities, are not material activities. Material activities means sense gratification, and spiritual activities means to carry out the orders of Kṛṣṇa. This is the difference. Sarvopādhi-vinirmuktaṁ tat-paratvena nirmalam (CC Madhya 19.170). Nirmalam means purified senses must be there. We are living entities. There must be senses. There must be desires. That is not possible, because we are living entities. If our senses do not work, if we do not desire, then what is the difference between the stone and myself? The stone does not move, the stone does not act, the stone does not desire. So if I become like stone, then what is the benefit? No. The nirviśeṣavādi, śūnyavādi, they want to make oneself like stone. That is not curing. They give up everything. Brahmā satyaṁ jagan mithyā. They . . . that is not mithyā but temporary. Anyway, they simply give up.
