P. 168 The Gospel of Sri Ramakrishna

Teachings of Swami Vivekananda - Cheerfullness

By the practice of cleanliness, the Sattva material prevails, and the mind becomes concentrated and cheerful. The first sign that you are becoming religious is that you are becoming cheerful. When a man is gloomy, that may be dyspepsia, but it is not religion. A pleasurable feeling is the nature of the Sattva. Everything is pleasurable to the Sattvika man, and when this comes, know that you are progressing in Yoga.  CW Vol. 1 P. 264

Teachings of Sri Ramakrishna

He who has realized God does not look upon a woman with the eye of lust.

Teachings of Holy Mother - Sarada Devi

These earthly ties are transitory.
Today they seem to be
the be-all and end-all of life,
and tomorrow they vanish.
Your real tie is with God.

Teachings of Sri Ramakrishna

"Besides, the children may be disobedient. There is no end of difficulties. Now, sir, what is the way?"

Sri Ramakrishna: "It is extremely difficult to practice spiritual discipline and at the same time lead a householder's life. There are many handicaps: disease, grief, poverty, misunderstanding with one's wife, and disobedient, stupid, and stubborn children. I don't have to give you a list of them. But still there is a way out. One should pray to God, going now and then into solitude, and make efforts to realize Him." P. 326 The Gospel of Sri Ramakrishna
