सर्वद्वारेषु देहेऽस्मिन्प्रकाश उपजायते | ज्ञानं यदा तदा विद्याद्विवृद्धं सत्त्वमित्युत

當知識之光透過此身體的所有門戶（感官）而放射時，那時就應當知道悅性（Sattva）已大大增長。
When the illumination that is knowledge radiates in this body through all the doors (of the senses), then one should know that sattva has increased greatly.
當某種屬性佔據主導時，它就會在人身上展現其獨特的特徵。正如茉莉花香遠播，知識也同樣向四面八方傳播。將答磨（Tamas）轉化為羅闍（Rajas），將羅闍（Rajas）轉化為悅性（Sattva）。現在，堅定地立足於悅性（Sattva）之中，你將獲得光明、純淨、和平與和諧的增長。悅性（Sattva）將引導你向上，你將被向上拉向至高之光。悅性飲食、持咒（Japa）、冥想、研讀聖典、獨居、與聖人為伴、歌頌神名與榮耀，以及調息（Pranayama）都將增加悅性（Sattva）。反省內觀，仔細觀察三德（Gunas），保持警覺，如同守門人。只允許悅性思想通過心智工廠的大門，抑制羅闍（Rajas），遏制答磨（Tamas）。當悅性（Sattva）佔主導時，心靈會平靜無波，內在和諧，完美寧靜。同時也伴隨著清晰的洞察力，理解力不被蒙蔽，具有穿透性的洞察。直覺之門或門檻敞開，感官不會追逐外在對象。感官是感官知識的通道，是真我感知的門戶。當光芒照耀身體的所有門戶，如眼睛、耳朵等（換句話說，當內心（Antahkarana）的智慧（BuddhiVritti）顯現時），知識便會產生。你可以透過知識的標誌來理解悅性（Sattva）佔主導地位。你也可以透過幸福的標誌來知道悅性（Sattva）正在增長。正如修行者透過知識和幸福的標誌知道悅性（Sattva）在他體內佔主導地位，同樣，他也可以透過知識的標誌知道羅闍（Rajas）和答磨（Tamas）正在逐漸減少。耳朵避開不應聽聞之事，眼睛放棄不應觀看之物，舌頭避免說不當之言，心靈不被感官對象所吸引。透過持咒（Japa）、冥想和自制，純淨逐漸增長。如果悅性（Sattva）或和諧增加，知識也會隨之增加。悅性（Sattva）是獲得真我知識的唯一可靠途徑，它奠定了知識的基礎。
When a particular ality becomes predominant? it reveals its distinctive characteristics in man. Just as jasmine scatters its fragrance far and wide? so also knowledge disseminates itself in all directions. Convert Tamas into Rajas and Rajas into Sattva. Now stand firm in Sattva. You will get increase of light? purity? peace and harmony. Sattva will lead you upwards. You will have an upward pull towards the Supreme Light. Sattvic diet? Japa? meditation? study of holy scriptures? living in seclusion? company of holy men? singing His Names and glories? and regulation of breath (Pranayama) will increase Sattva.Introspect. Look within. Watch the Gunas carefully. Be vigilant. Stand as a doorkeeper. Allow only Sattvic thoughts to pass through the door of the mental factory. Check Rajas. Curb Tamas. When Sattva predominates there is unruffled peace of mind? inner harmony? perfect serenity and tranillity. There is clarity or clear vision also. The understanding is not clouded. There is penetrative insight. The door or threshold of intuition is wide open. The senses will not run towards external objects.The senses are the avenues of senseknowledge. They are the gateways of perception for the Self. When light shines in all the gates of the body? such as the eyes? the ears? etc. (in other words when there is the manifestation of the BuddhiVritti of the Antahkarana)? then knowledge arises. You can understand by the mark of knowledge that Sattva is predominant. You can also know that Sattva is increasing by the mark of happiness. Just as the aspirant knows that Sattva is predominant in him by the marks of knowledge and happiness? so also he knows by the mark of knowledge that Rajas and Tamas are gradually decreasing.The ears shun whatever is improper to be heard. The eyes abandon what they should not look at. The tongue avoids to speak anything that is not right to speak of. The mind is not attracted by the sensual objects. Purity thus increases gradually by Japa? meditation? and selfrestraint. If there is increase of Sattva or harmony? there is also increase of knowledge. Sattva is the only sure means for the attainment of the knowledge of the Self. It lays the foundation of knowledge.
