Kolkata, Jan 13 (IANS): Tibetan spiritual leader the Dalai Lama Tuesday said the ancient Indian psychology is "highly developed" in comparison to modern one, but unfortunately the people of the country are forgetting their ancient school of thought.

"We need more studies on the ancient Indian psychology. Modern psychology, compared to ancient Indian psychology, including Buddhist psychology, looks like kindergarten level. Ancient Indian psychology is highly developed," he said, delivering a lecture at the Presidency University here.

Terming Indians as "gurujis" (teachers) in the field of ancient Indian psychology, the Dalai Lama acknowledged the role of the country in disseminating its tradition to his community.

"Historically and traditionally, you (Indians) are our guru (teacher)... We learn everything from you...We are your chelas (disciples)," he said.

"Unfortunately, our gurujis are forgetting these things in recent centuries and not paying much attention, and we disciples are catching this knowledge over thousand of years. So now, disciple's knowledge about ancient India is better than guru's knowledge," he said.

The Dalai Lama highlighted the co-existence of multiple religions in India.

"India's constitution is based on secularism. There is no other way except secularism. Respect all religions and also non-believers. Today, the world needs that. I am a messenger of the ancient Indian thought. India could be an example that (people of multiple) religions can live together," he said.
