స్వామి శివానంద సూక్తి

The last thought determines the next birth. The last prominent thought of one’s life occupies the mind at the time of death. The predominant idea at the time of death is what in normal life has occupied his attention most. The last thought determines the nature of character of the body to be attained next. As a man thinketh, so shall he become.

- Swami Sivananda
