There is no place for emotions in spirituality

स्वधर्ममपि चावेक्ष्य न विकम्पितुमर्हसि ।
धर्म्याद्धि युद्धाच्छ्रेयोऽन्यत्क्षत्रियस्य न विद्यते ॥ – श्रीमदभगवादगीता(२.३१)

swadharmapI chaavekshy na vikampiturmahasi
dharmyoddhi yuddhachyoNyakshatriyasya na vidyate

Meaning: Thus, as per your own Dharma too, you are not worth cultivating a fear; meaning you should not be afraid; because for a Kshatriya (warrior), there is no other prime duty than fighting a Dharma-based war.
Implied meaning: There is no place for emotions in spirituality. Here, Shri Krushna is telling Arjun, that he should follow his Dharma as per his Varna(class). And the Dharma of a Kshatriya is to fight a war, even if the enemy side includes his kith ad kin, for, there is no bigger duty for a seeker than following the Dharma. Any seeker who does not do his/her Karma, trapped by the six foes viz “desire, anger, greed, attachment, ego and jealousy actually does Adharma. In spirituality, one must understand the difference between Bhav (spiritual emotion ) and Bhavana (emotion, or feeling), only then can one progress on the path of Dharma. Emotion means what our mind says and Bhav (spiritual emotion) means what God wants us to do. This is what Dharma recommends. Here, Arjuna is overpowered with emotion on seeing his close relatives, teachers and friends as his opponents in the battlefield and his emotions envelope him. Hence, God Krushna has to remind him of his Dharma as per his Varna and let go off his emotions. Thus, He, motivates him to fight. To imbibe the difference between Bhav (spiritual emotion) and Bhavana (feeling), the seeker must analyse every incident if his action will please the God and also if it is in accordance with Dharma. Thus, after making this kind of attempts with consistency, the seeker is able to control his emotions and can follow Dharma on the basis of prudence and discrimination.
