I found a sutta that said exactly what Mr. Lal means. I don’t know if he had already posted this sutta in one of these articles.
Snp 2.1 Ratana Sutta: Jewels Discourse
9. Ye ariyasaccāni vibhāvayanti
Gambhīrapaññena sudesitāni
Kiñcāpi te honti bhusappamattā
Na te bhavaṁ aṭṭhamaṁ ādiyanti
Idam’pi Saṅghe ratanaṁ paṇītaṁ
Etena saccena suvatthi hotu
Those who comprehend the Noble Truths, well taught by the Buddha of profound wisdom, no matter how negligent, would not take an eighth existence. In the Saṅgha is this precious jewel. By this truth, may there be well-being!
10. Sahāva’ssa dassana sampadāya
Tayassu dhammā jahitā bhavanti
Sakkāyadiṭṭhi vicikicchitañ ca
Sīlabbataṁvā’pi yadatthi kiñci
Catūhapāyehi ca vippamutto,
Cha cābhiṭhānāni abhabbo kātuṁ
Idampi Saṅghe ratanaṁ paṇītaṁ
Etena saccena suvatthi hotu
For one who has attained the correct view, three fetters are abandoned: self-centered view, doubt, and clinging to wrong practices. Freed from the four planes of misery, he cannot commit the six major wrong-doings that lead to hell. In the Saṅgha is this precious jewel. By this truth, may there be well-being!
11. Kiñcā’pi so kammaṁ karoti pāpakaṁ
Kāyena vācā uda cetasā vā
Abhabbo so tassa paṭicchādāya
Abhabbatā diṭṭha padassa vuttā
Idampi Saṅghe ratanaṁ paṇītaṁ
Etena saccena suvatthi hotu
Though he might do some evil deed by body, speech, or mind, he cannot hide it; such is impossible for one who has seen the Dhamma. In the Saṅgha is this precious jewel. By this truth, may there be well-being!
