Among the eight sources of Wealth, the ‘Nidhi’ titled Padma enriches wealth by the successive generations; this source of Wealth multiplies by way of business deals in the form of vessels and ornaments made of Gold, silver etc. enabling the performance of Propitious Acts like Yagnas, Charities, Construction of Temples; this source is essentially of ‘Satvika Guna’. The Nidhi called Maha Padma which is also of Satvika Guna deals with exchange or further acquisitions of high-value jewellery and precious stones like diamonds for performing sizeably big tasks of Maha Yagnas and such other huge magnitudes; in this case the source of wealth involves very substantial investments or expenses for seven or more generations. Another source of wealth is of Tamasika nature called Makara which is utilised for enabling tasks like wars, maintenance of defence forces etc. but that kind of source might last for a generation or so. The source of wealth denoting Kacchapa is basically land-based, used for investments or expenses for ‘Dharma Karyas’. Mukunda is another source of wealth which is used for the Promotion of Fine Arts or such other acts of personality development involving Rajo guna for leading happy and satisfying lives. Essentially meant for meeting expenses towards ‘Athithya’ (taking care of guests), social functions or personal obligations, another source of wealth is long standing for seven generations or so called Nandaka involving Rajo guna again.The seventh source of wealth is called Neela of Tamasika / Satvika nature again in which buying or selling is involved of items like Dhanya( Farm Produce), Vastra (clothing), or saleable material involving transactions lasting for a medium run of generations, say for two or three. The Eighth source of wealth known as Shankha is mostly for individual utilisation but not even for his family even and hence is basically for tamasika end-use.
