Dayau or Compassion is a fundamental teaching of the Sikh religion and teachings can be found on DAYA. The other four qualities in the arsenal are: Truth (Sat), Contentment (Santokh), Humility (Nimrata) and Love (Pyaar). These five qualities are essential to a Sikh and it is their duty to meditate and recite the Gurbani so that these virtues become a part of their mind.
You have no compassion; the Lord’s Light does not shine in you.
You are drowned, drowned in worldly entanglements. (4)— Sri Guru Granth Sahib page 903
This concept says to not ignore tragedies that take place in the world but to face them head-on and do whatever is possible within ones means. As a Sikh you must feel the pain and suffering of other people involved in any tragedy.
Daya in Sikhism
Daya (usually spelt daia in Punjabi), from Sanskrit "Day" meaning to sympathize with, to have pity on, stands for compassion, sympathy. It means ‘suffering in the suffering of all others’. It is deeper and more positive in sentiment than sympathy. Daya, cognitively, observes alien pain; affectively, it gets touched by it and moves with affectional responses for the sufferer; and cognitively it moves one to act mercifully, pityingly, with kindness and forgiveness. One imbued with daya “chooses to die himself rather than cause other people to die,” says Guru Nanak (GG, 356).
Daya is a divine quality and a moral virtue highly prized in all religious traditions. In the Sikh Scripture, mahadaial (super compassionate), daiapati (lord of compassion), daial dev (merciful god), karima, rahima (the merciful one), etc., have been used as attributive names of God (GG, 249, 991, 1027, 727). In Sikh ethics, too, daya is inter alia, a basic moral requirement, a moral vow. “Keep your heart content and cherish compassion for others; this way alone can your holy vow be fulfilled” (GG 299).
At the human level, one can comprehend feeling of another’s anguish, but as a theological doctrine it is to risk allowing suffering in God’s life. This has often caused much controversy in theological circles. God does not suffer in the sense of pain from evil as evil, but may suffer compassion (daya) as bearing the pain of others to relieve them (of pain as also of evil). That is why at the time of Babar’s invasion of India, Guru Nanak, when he witnessed the suffering of people, complained to God:
So much agony were they put through
So much anguish did they suffer —Were you not, O God, moved to compassion?— (GG, 360)
The Guru, in the image of God, is also daial purakh (compassionate being) and bakhasand (forgiver)—GG, 681.
Daya is a virtue of the mind. In Indian thought, virtues are classified into (i) those of the body: dana (charity), paritrana (succouring those in distress), paricharana (social service); (ii) those of speech: satya (veracity), hitovachana (beneficial speech), priyavachana (sweet speech), svadhyaya (reciting of Scriptures) and (iii) those of the mind which, besides daya, also include aparigraha (unworldliness) and sraddha (reverence and piety).
In Sikh thought daya is considered the highest virtue:
The merit of pilgrimages of holy places sixty-eight,
and that of other virtues besides, equal not compassion to beings.— (GG, 136)
Daya, in fact, is considered to be Truth in action:
"Truth dawns when truthful counsel is accepted,Seeking familiarity with compassion one gives away virtuous charity."— (GG, 468)
Daya is, in reality, true action or action par excellence (karni sar)
as are truth and contentment, the other two high virtues— (GG, 51)
