This is the definition of mahātmā. When one engages his senses for the satisfaction of the supreme senses... But unfortunately, we define the Supreme as having no senses. Nirākāra. No hands, no legs, no eyes, nothing, no senses. Simply I have got my senses. And who manufactured me, he has no senses. But that is not fact.
If I have got my senses, my father, who manufactured me, he has also senses. This is right conclusion. How is that? I have got my senses, I have got my propensities, I have got my form, and why these things should be denied to my father, and especially the supreme father? Therefore Bhagavad-gītā says that avyaktaṁ vyaktim āpannaṁ manyante mām abuddhayaḥ, paraṁ bhāvam ajānantaḥ (BG 7.24). They do not know. But actual fact is that when our senses will be sacrificed for the satisfaction of the supreme senses, then our life is successful. Hṛṣīkeṇa hṛṣīkeśa-sevanaṁ bhaktir ucyate (CC Madhya 19.170).
It is not that nullifying my senses, God's senses, every... No. Senses are there. My senses are there, and God's senses are there. But when my senses will be engaged in satisfying the Supreme senses, that is my perfection of life. Hṛṣīkeṇa hṛṣīkeśa-sevanaṁ bhaktir ucyate (CC Madhya 19.170).
So that can be begun with sevonmukhe hi jihvādau (Brs. 1.2.234). Because we meet together and talk so many nonsense in political conference, social conference, scientific conference, tongue going on. Day and night, conference is going on. And another business, eating process, sense gratification. If people are asked, "Please come here. Chant Hare Kṛṣṇa," they are not at all interested. And invite him in some political meeting and talk all nonsense. He is very much interested. Yes. This is called māyā. So we have to convert this. Instead of engaging senses for talking nonsense, we have got so many books, so many talks about Kṛṣṇa. Why not take this? You can go on on, Śrīmad-Bhāgavatam, about Kṛṣṇa. Bhagavad-gītā. Go on talking, and go on eating kṛṣṇa-prasādam. Sevonmukhe hi jihvādau, chanting Hare Kṛṣṇa mantra, sevonmukhe hi jihvādau svayam eva sphuraty adaḥ. Then self-realization is guaranteed.
