BG Chap 10 - Kṛṣṇa is the origin of all qualities
There are various qualities and states of the living beings which all arise from Kṛṣṇa. They are: Buddhi (intelligence) is the ability to make subtle distinctions and thereby discern the fine meaning of things. Jñāna (knowledge) means to distinguish spiritual from material. Asammoham (non-bewilderment) is absence of confusion. These three qualities, though they appear to bring about knowledge of Kṛṣṇa, are not causes of that knowledge. The other states seen in people also come from Kṛṣṇa: Kṣamā is tolerance. Satyam is to speak the truth for others’ benefit. Dama means control of external senses such as the ear from useless sense objects. Śama means controlling the internal sense, the mind. These qualities are sāttvika. Sukha (happiness), which means regarding something as favorable is sāttvika, whereas duḥkha (sorrow), which means regarding something as unfavorable is tāmasika. Bhava (death), abhāva (death) and bhaya (fear), which arises from regarding something as a future cause of suffering are all tāmasika.
Abhaya, which is fearlessness, arising from knowledge is sāttvika, but if it arises from rajas or tamas, it is rājasika or tāmasika. Ahiṁsā (non violence), which means not giving pain to other entities, and samatā, which means absence of attraction and repulsion or seeing others as one’s self are sāttvika. Tuṣṭi (satisfaction), if unconditional, thinking that whatever comes is due to one’s karma is sāttvika, but if conditional is rājasika. Tapa (austerity), which means suffering of the body prescribed in the Vedas, Dāna (charity), which means offering one’s enjoyable items to a qualified person, Yaśa (fame), which means being known for good qualities, and ayaśa (infamy) are all either sāttvika or rājasika depending on them being conditional or unconditional. All these arise from Kṛṣṇa’s energy, and because He is non different from His energy, it is said they arise from Him.
All these qualities are manifest throughout the universe in human society and in the society of the demigods. Now, for one who wants to advance in Kṛṣṇa consciousness, Kṛṣṇa creates all these qualities, but the person develops them himself from within. One who engages in the devotional service of the Supreme Lord develops all the good qualities, as arranged by the Supreme Lord.
