When the sadhaka is firmly established in the practice of truth, his words become so potent that whatever he says comes to realization.

Verse 2.35

अहिंसाप्रतिष्ठायं तत्सन्निधौ वैरत्याघः ॥३५॥

ahiṁsā-pratiṣṭhāyaṁ tat-sannidhau vairatyāghaḥ ॥35॥

When non-violence in speech, thought and action is established, one's

aggressive nature is relinquished and others abandon hostility in one's

presence.

Verse 2.36

सत्यप्रतिष्थायं क्रियाफलाअश्रयत्वम् ॥३६॥

satya-pratiṣthāyaṁ kriyā-phala-āśrayatvam ॥36॥

When the sadhaka is firmly established in the practice of truth, his words become so potent that whatever he says comes to realization.

Sutras 2 .35-39 describe the effects of observing the five yamas.

When the yogi has thoroughly understood the nature of violence, he is established firmly in the practice of non-violence. 

Peace in words, thoughts

and deeds, whether awake or dreaming, is a sign of goodwill and love towards all.

In the closeness of a yogi, men and animals who are otherwise violent and antipathetic towards each other, give up their conflicts and exhibit

friendliness and mutual tolerance.

Most of us think we tell the truth, but truth is causal, not integrated and

cellular. For instance, if we say 'I will never eat chocolates again', as long

as one cell of our body holds back and disagrees with the others, our success

is not assured. 

If the stated intention is totally whole-hearted, not one cell

dissembling, then we create the reality we desire. It is not our mind, but the inner voice of our heart which has the power to implement our intentions.
