aitri (friendliness), Karuna (compassion), Daya (sympathy), Visva-Prema (cosmic or universal love), Kshama (forgiveness), Dhriti (spiritual patience), Titiksha (power of endurance, forbearance) and tolerance are Sattvic qualities of the mind. They contribute to the peace and happiness of human beings. They should be cultivated to a very high degree.
Love and pity make the mind soft. Pity has the characteristic feature of evolving the mode of removing pain; the property of not being able to bear seeing others suffer; the manifestation of not harming; the proximate cause of seeing the need of those overcome by pain. Its consummation is the suppression of harming; its failure is the production of sorrow.
Patience, tenacity, Utsaha (perseverance) and determination are indispensable for success in Self-realisation. They should be developed to a maximum degree, particularly by spiritual aspirants. When you meditate on OM, when you assert yourself as Brahman in the morning meditation, you will gain a lot of strength. That will help to give you courage that is needed for the progress in the spiritual path. Many difficulties on the path of Truth are to be overcome through the help of fortitude and endurance (Titiksha). These qualities are the forms of courage. Fortitude is mental power of endurance. It is firmness in meeting danger. It is power of resistance.
The Ten Lakshanas Of Dharma
"Dhritih kshama damo'steyam saucham-indriyanigrahah
Dheer-vidya satyam-akrodho dasakam dharmalakshanam"
Patience, forgiveness, control of mind, non-stealing, external and internal purity, control of Indriyas, knowledge of Sastras, knowledge of Atman, truthfulness and absence of anger are the ten Lakshanas of Dharma according to Manu.
Your thoughts must agree with the word. This is Arjava (straightforwardness). Practise this. You will derive wonderful benefits. If you practise Satya for twelve years, you will get Vak-Siddhi. Whatever you speak will come to pass. Chinta (anxiety) will vanish. You will be free from committing many evil actions by speaking the truth.
Patience, perseverance, application, interest, faith, zeal, enthusiasm, determination are necessary during Sadhana. Sraddha and Bhakti are noble Vrittis that help a man to free himself from bondage. These virtues have to be cultivated. Then only is success possible. Look at the various difficulties that crop up in the way. The spiritual line is, therefore, difficult. Very few take to the path, one in thousands (according to the Gita). Out of them very few succeed. Many give up Sadhana when they are half-way, as they find it difficult to pull on till the end is reached. It is only the Dhira (firm) with Dhriti, Dhairya and Utsaha that reaches the goal of Sat-Chit-Ananda state. Hail, hail, to such rare noble souls!
