Good actions. (Glossary for the Vahinis)

The Samskaras make a man or mar the jiva, they are steps which take all Jivas to the goal. Samskaras make the jiva wade through loss and grief. Through good Samskaras alone can man attain the Lord; so, every jiva has to be wholly engaged in Sat Karma. Sat Karma is the authentic Puja. It is the best form of remembering the Lord. It is the highest Bhajan. It spreads love without distinction and difference. It is service done as the duty to the Jiva. Be engaged in such Karmas. Revel uninterruptedly in the thought of the Lord. This is the royal road to the goal you have to reach. (Prema Vahini, 1975)

Every student should undertake Sat karmas (good actions), which lead to Citta-shuddhi (purity of mind). Where there is purity, there will be Jnana Siddhi, dawn of wisdom. These are all within yourself only. You need not search for them anywhere outside. (ICS , p. 171)
