Keep a picture of Sri Ramakrishna with you. Whenever lustful feelings arise, you should look at the picture intently. You will find that the senses will gradually be gathered in and the mind will be free from lust. (p.428)
His fame rests mainly on his Aryabhatiya, but from the writings of Varahamihira (Sixth century AD), Bhaskara I, and Brahmagupta (seventh century) it is clear that earlier he composed the Aryabhata Siddhantha (voluminous) is not extant. It is also called Ardharatrika Siddhanta , because in it the civil days were reckoned from one midnight to the next; 34 verses on astronomical instruments from this have been quoted by Ramakrishna Aradya.
...if we study the Gospel of Sri Ramakrishna, we find that though He taught the truths contained in the Upanishads, He illustrated these principles to us by methods that are Tantric in origin and content. His worship of and devotion to Mother Kali, Sri Krishna, Mother Sita, Lord Chaitanya, Lord Shiva, and others, reveal His wonderful Tantric nature and point to the many ways of practicing the Vedic truths.
The children of Sri Ramakrishna are Vaidikas in essence, Tantrikas by path and process.
Ramakrishna attained god consciousness through Vedanta, the philosophy that has evolved from the teachings of the Vedas, a collection of ancient Indian scriptures,that are the world’s oldest religious writings. According to Vedas, ultimate reality is all pervading, uncreated, self-luminous eternal spirit, the final cause of the universe, the power behind all tangible forces, and the consciousness that animates all conscious beings.
