In plain words
Are the services you do satisfying to you? Or are you doing them with show, to please others? As long as this show is there, joy will not come to us. As long as this show is there, Ahaṅkāra will not die. Unless Ahaṅkāra dies, the principle of the Ātma will not be understood. So, first of all, we must kill this show. Through that, this Ahaṅkāra too will die. Our natural bliss will come forth in us. We must win our natural bliss. Here, in the Bhagavad Gītā, two words are used: svadharma and paradharma. We think svadharma means the dharma of caste, creed and class. No, no. Sva: the Ātma. The Dharma of the Ātma itself is svadharma. Paradharma means the dharmas of the body. That is, what concerns caste, creed and class. All the rites, yajñas, yāgas and the rest, belong to paradharma. All these are for the sake of the other. We must hold that the paradharma the Bhagavad Gītā speaks of is only the dharma that belongs to the body.
The very first verse of the Bhagavad Gītā is 'dharmakṣētrē kurukṣētrē'. Which is the Dharma-kṣetra? Which is the karma-kṣetra? The heart itself is the Dharma-kṣetra. The body itself is the karma-kṣetra. So the Dharma-kṣetra lies within the body, which is called the karma-kṣetra. So all the karmas done with the body are the karma-kṣetra itself. Every man is a pilgrim to the Dharma-kṣetra. There is no escape from doing karmas. These karmas go on being done naturally. Our breathing in and breathing out are karmas. The flow of our blood too is karma. Our words are karma. Our games are karma. Everything is full of karma. So the body is full of karma. The heart alone is the Dharma-kṣetra. From there the feelings must come. From there the words must come. All the rest is somewhat artificial. They are artificial. So all that is outside us is artificial. Only what is within us is real. art is outside heart is inside. We must follow the heart. This alone is the chief teaching of the Bhagavad Gītā. Kurukṣetra does not mean some field near Delhi. It is the doing of outward karmas. So our body itself is Kurukṣetra. Our heart itself is 'the Dharma-kṣetra: dharmakṣētrē kurukṣētrē samavētā yuyutsavaḥ', the 'I' in which the two have joined. Māmaka means that which is bound up with possessiveness.
