In plain words
The words that come out through speech, and through deeds: these we must experience. This has been called ‘trikaraṇaśuddhi’. That is: the proper study of mankind is man. The oneness of the three, the resolve of the heart, the vision of the eyes and the karma of deeds, is itself true fullness. So however many books worth reading you read, however many elders you visit, however many kinds of sādhana you perform, if there is no samyak dṛṣṭi, all these are useless. The Buddha himself, recognising this supreme truth, first said that samyak dṛṣṭi is most essential for the sādhaka.
The heart becomes pure through spiritual inquiry
Dilip Chand said the other day: ‘Help ever, hurt never.’ Try to help others as far as you can. Do not set about hurting anyone. Not only by karma, not only by speech, nor only by deeds, nor only by the heart: in every way we must set about the effort of helping others. If it is not possible for you to help, just do no harm. That itself is the great ‘help’. We must let such feelings arise in us, believe in so beautiful a divinity, and make sacred Prakṛti fruitful. When we develop samyak dṛṣṭi, ‘samyak vāk’ arises. Only after we first develop our vision does sacred speech come out from within the heart. Only words that come from the heart are true words. Words that come from the tongue are not truthful words. Nor are words that come from the throat real. It must arise from the heart. This heart is ever full of compassion. That is hṛt-daya, hṛdayam. So we must fill what is called the heart with compassion alone. Then samyak dṛṣṭi, samyak vāk, samyak śravaṇam and samyak karma all take shape as samyak dṛṣṭi. So with every word and every look: “Is this arising from the heart?
